I received  3rd party charges all within 1 minute for a total of $10.49 I am on the phone to telstra as I am typing this and using some of the advise as above:
SMS baring
refusing to pay the $10.49
will go to the supervisor then communication ombudsman if not a satisfactory outcome
and also to the police as this is just plain theft wrapped up as a billing issue
I will not be communicating with Open Market because this is an issue with telstra billing

As the same as the rest of you. 4 calls same day same time. I contact Telstra and was advised to call 1800 852 324 to cancel the subscription I had not subscribed to in the first place. After asking to speak to a supervisor I have been credited with the call charges.

I think mine came from an Apple iPad competition too but after they kept constantly sending me more messages I replied with STOP and I have had no more since. So I have 15.50 of 'separate purchases' al in the space of 1 minute on 5 Nov and hope that's the end of it.

Just opened my Telstra a/c to find I have been scammed of $30.25 rang Telstra who immediately refunded the money. Have blocked their 1300 number but is this going to work?

These calls are from the company Openmarket Pty Ltd - ABN 98108798223. They run scams in which they send unwanted premium SMSs which were not requested to people and charge them $6.60 for this 'service'.

If you have been scammed in this way firstly contact your phone company and tell them to bar premium SMS content. This will stop the scam SMSs. When you speak to your phone company tell them that you refuse to pay for the Openmarket SMSs. The phone company will probably agree to withdraw any such charges and may refund charges which you have already paid. If they are not prepared to do this, complain to the Telecommunications Obudsman and you will probably get your phone company changing their mind.

Hi - I have been scammed too. Rang telstra who blocked the texts once I realised what was happening. My electronicly received phone bill went missing in cyber space too somehow . I received a late notification and incurred additional costs from telstra for an overdue account . Telstra told me to call Open Market to be refunded ? Was effectivley fobbed off by OM and told to call 'Mobile Broomestick' - guess what they are based in Singapore 1300881163.  The woman I sppoke to was pretty rude and of course didnt offer to help , refund etc. She insisted I had registered on line and replied via text to confirm my subscription.This is absolute rubbish.I am seeking advice from consumer affairs.

between 19 aug to 16sept $75.00 charged what for!

I have been charged too:
$80  +  $80  = $160 !

Well, I have just checked my current Telstra account and what should I find but a section showing
"Third Party Purchases" between 12th & 15th July 2013 for $30.50 !

Interesting to note that all charges were at the same time and from a company I have never heard of ?
Contacted Telstra to complain about these unauthorised charges after finding hundreds of other people had similar issues with this company "Open Market Pty Ltd at Potts Point, Sydney.
These calls were coming from a number 1994 8844 so look out !

Telstra have now credited my account, locked off my mobile against this number and recommended I also contact this number and SMS the word "STOP".
This is a huge SCAM. How is this company still in business - Telstra needs to shut it down.

This is a scam - they got me too. for $80. Each time they send three of the same messages within seconds of one another - each of the three costs $6.60. The messages offered no option to request they stop or a phone number to ring. I was not aware of the cost until I receive my Telstra bill which quoted a number to ring to stop the messages - I did so and they seem to have stopped - emailed the ombudsman who hen advised Telstra - Telstra undertook to reverse the charges today - so I await the credit to my account - I propose to escalate this further with the Ombudsman as its a blatant Scam. Telstra advises in future to SMS back the word STOP when confronted with this type of issue.

Another victim of this ridiculous scheme - $55. Calling Telstra today to see if I can be reimbursed. Called 1300 136 616 to unsubscribe - should stop all future charges from them.

telstra will help you they just blocked it from accesing my number and credited me the charge . it was for $94.50 .telstra were very nice and helpful about it all.

seems like we have the same problem, $6.60 x 3 on June 10 on telstra account all at the same time.  about to try and contact telstra and block the number on our mobile.  yeah, pays to check the bill with a fine tooth comb!

OpenMarket are a mobile aggregator from their website, so they're not the ones actually running the charges - they just provide connections for companies. You should be able to text STOP in reply to the messages - this is just a normal SMS cost.

We have been getting charged 20.00 a month for god knows how long cause we having been getting a bill, some how they put a stop to it, we went to Telstra and ask why we were getting a bill and what this third party purchases are, they said it must be something we are doing with our iPhone but when the charges go on we are at work ????, I questioned it they said it happens some times, I rang the number and was. On hold for a long time, to get a message to say that the person I was ringing wasn't there, how do I get this stopped

Did you get a refund I have it all over my mobile bills for months now

The messages come from an Apple Ipad competition.  To have answered the questions they sneek in a subscrition in order to continue.  This is how they get away with the charges, and there is aparently no way of getting your money back, you have to unsubscribe to stop them.  The number to call is 1300 136 616.......They stung me a hunge a month the rotten b*****ds!  Hope this helps   :)

Last month $75 & this mth  $60  . I win don't open  messages . I delete them all the time . Telstra have been helpful but the no. The no. They gave to screamSTOP these messages is not an sms no. &Davis me to ring . Ha  no one answers it

Thankyou for your input I am up to $105 went to Telestra myself today and they just fobbed it off and said not their problem
At least with your info I have something to go off I have a friend who is a Journalist for a TV station might have words with her and see if we can get the ombudsman telestra get altogether and see who blames who and which one is going to pay back all the monies taken from us all
do you know is this the closest office NSW anymore info would be greatly appreciated Kind Regards Donna

Got charged 2 x $6.60 on same day and time. Read message and cancelled receiving calls on mobile service. No further charges but will monitor January carefully. Will also contact Telstra to have them blocked. Will also check out blocking the number myself on my mobile.

Wow yes htis is happening to me as well, when asked Telstra to block them, they said its up to me, what aload of crap from Teltrs services.

Waiting now for answer from Telstra, over the past 2 months been charged a total of 120.00

I have had the same problem,i got in touch with Telstra and they blocked them from sendig anything to my phone,hope this helps

I have had this happen to me, has anyone been able to stop them doing it, i have been charged over  $80, need to know what to do.  Will telstra help if I ring them

How can I get OPENMARKET (1300760083)  calls blocked by TELSTRA. This is the second month I have been stung for $20.00, apparently provide by NXTELE

"Ye" I am getting charged even when they SMS me and I don't answer. Had to get Telstra to block them.

Yep. Same here. 10 x $6.60. 4 calls billed at the same time. 2 more each for next 3 days. Amazing that telecommunications Ombudsman has had so many complaints about this company yet nothing is happening.

Same - 4 items at $6.60.  Range to cancel as advised by Telstra, automatic reply, so hope info fed in will actually cancel.

wow they just got me as well, $79.20 worth of charges!!

i have had two bills from telstra with over one hundred dollards in charges.  telstra not interested and these people cannot be stopped

They're scamming me now as well. 2 x $6.60 charges each week for the last 5 weeks. Each of the 2 charges is in the same minute.

Telstra still haven't refunded last months scam charges (and obviously haven't done anything about blocking these criminals). They're obviously happy to keep picking up their share of the charges!

How can this happen?
