I have started getting calls from 02330754393.  Checked this number and find it is from Gamma Telecom Holdings.  Don't know where they got my number as I am ex-directory.  No-one ever speaks when I answer.

I received several calls in the same week, each time they ring they say a different company name. The company keeps asking if I have a mortgage or loan and to see if I can claim back any PPI. When they rang again I said are you the same company using a differnet name every time you ring me, but they denied it. Very annoying.

Calls alot during the day...when trying to call it back it says the phone number can't be dialed

Had a call from this number. I picked up but they hang up. tried to call my service provider and they advised me to contact the police.

Missed call on mobile (UK)

Called back and told "Sorry but this mailbox is full and cannot accept messages" in an American accent. Hope I don't get charged for it.
So annoying

I received 2 calls from this number this evening trying to sell me Vonage VoIP services.

After transferring me to a supervisor because they could not accept I already get services cheaper than they provide, he hung up, twice, as it appears he did not believe me.

Didn't have chance to find out how they knew my number

ththis number keeps calling me at odd times, of day and night, only rings a couple of times, but allways to my mobile

havent managed to speak to them yet, when i call the number it says it doesnt accept incomig calls

They have called me twice today and I questioned which company they were from and then said Talk Talk

I keep getting calls from 02030234291 every day to my mobile does anyone have the same problem

I got a call from 02033705949 which shows as Gamma Telecom Holdings ltd at 2.30am (4th may 2009). I have no idea who it is or why they are calling at stupid o'clock. I left it to go on the answer phone & they hung up.
I'm really worried as I'm a single mum & I can't afford to lose any money. Why don't these people get off their fat, lazy a**** and get a job instead of stealing money off hard working, honest people.

I got a call last night but I wasn't in, but there was a message on the answerphone and the fella was just saying, Hello, Hello Hello, then he hung up. I done a 1471 and got this number, tried to call it back and the this mail box is full message.

Rang 118 500 to see if they could tell me who it was but they cant trace a number back, came on here and found this thread, I am on O2 and Sky broadband, seems like O2 is the common theme here.

0203 006 3103
I recieved a call at 17:35 hrs on 28th feb 2009 again no one answered
and they hung up after 4 or 5 secs.I phoned the number back and I got an
answer machine saying "this mailbox is full". sounds like a scam.

I have received calls from this number 203-006-3103 3 X's in the last week and they just hang up when the phone is answered or they do not leave a message. I am a cell user in Arizona and have no clue who this would be.

Caller id caught this one.  The number is 203-006-3103, they never leave a message.  The caller id says the call is from Conneticut.  I have held off calling them, not sure what sort of callers I am dealing with

I just got a call from 2030063103. I have no idea who it was, and I didn't pick up, but I looked it up and this was the page I got. I guess they call a lot of people. I'd really like to know who this is.

I am constantely getting calls from this # on my cell phone. tried calling it back and was told I could not call an international phone #. Tried calling it from a land line, and just got a recording. How can I block this stupid #.????

This number keeps calling my house asking for a Katrina.. there is nobody by the name where i live.. keeps calling and say they aren't going to stop and claiming we are running from them. My brother in law and fiance have gave him a piece of their mind

Got a call on my cell from 203-006-3103, missed the call, tried to call back, recording said number could not be completed as dialed.

the same number appeared on my caller id..no one answered but it is a strange exchange.  i didnt call the number, just checked it out on the internet first.  keep me posted.

I keep getting these calls and same as everyone else-no-one speaks and when I called back the mailbox was full so an American sounding woman said. It's getting annoying now!

asian sounding chap called last night wanting to know several things. told him to get off the line and hungup

I get constantly rung up by these people, but they never say anything, so I now just let the answer machine kick in, but they never leave a message. This is really annoying. I`m also ex directory and with Virgin Media, so it must be something to do with them.

said they were from bt broadband and wanted to change my contract to a cheaper one. they then asked to check bank details which is when i said i wasnt interested and wouldnt do anything over the phone. promised to send an email and ring back in half an hour but as yet nothing has come through. mf

This number rang our house phone at 2.09pm... my mum answered it and she said there was some kind of music playing?? But she just hung up.
I mean, I've been getting these scam calls on my mobile, but never on the house phone. I'm with Virgin Media so I don't know if anyone else is with them and had this same number call.
It's pretty annoying!!!

Someone called me with that number 02030063103 everyday for 2 days now on my landline phone.  I usually wait and listen to the auto-reply on my machine, then after the tone, it was like someone didn't say anything but moving his phone around (like crack crack)and some breathe and for 2-3 seconds they would hang up.  

I feel funny that these people are made in pain to do things so nonsensibly and they can keep doing that.  Don't they have families or other more useful things to do or look after in life, I know economic recession has been everywhere in the world but they shouldn't be this frustrated !!!  

I recommend if they do not have anything to do, just go to church or any sacred places, this should help them to think more about their life rather than giving all round phone calls to everybody, you know you're wasting your time and life is short dear !!!
