0303 303 0303 is the general enquiries line for Anthony Nolan. It's a charity that donates blood stem cells to people with leukaemia etc. Maybe you signed up to the donor register online?

This number keeps calling,has for weeks now, and never leaves a message.  I do not answer until I know from a message who is calling.

This number keeps calling my house phone. They call about 3 or 4 times a day, at the minimum they call two times a day. I have no clue who this is and they never answer. who is this and how do i get them to stop?

Today was the first time this number called me and hung up. I'm not wasting any time. I'll file a complaint to the National Do Not CAll Registry.

These are coming to my cell phone? Don't know them and have not given out my cell # online for nothing. Consistent calls, 2 to 5x a day starting at 6am and going til 6pm. They never leave a message and when I called the number back it said it was disconnected??!!! Definitely an extension for a telemarketing firm.

Just got a call from this number for my husband. Said he wasn't here, and they hung up.

first call just a minute ago...don't know who this is and i wont answer!!!

Received a call asking for David, regarding business information. I told them there was no David at this number, and to please stop contacting me. They then tried to shift their tactics to sell to me. I asked to be placed on their do-not-call list and hung up.

I received calls from this number and it stopped. But now again keep calling. Mostly I didn't pick up. But today I had time and picked up. Woman sayd Hello? and asked my name. I said yes speaking and hang up. What it is about? I am afraid if these people  ID thieves what should I do. How to stop it?

called me and left no message.
2/13/10.

I receive calls on cell phone from this number at least 5 times a day, 7 days a week. Yes, even Sundays. I've never answered or called them back. No messages have been left on my voicemail. I have no idea how they got my phone number or how to go about getting rid of them.

i called the number back and it said the number you have dialed is  temporary not in  service? they have called me 5 times this week

They Just called and when I said the person was not there they were looking for she just hung up on me. that is rude as hell and I wish there was a way to call these b*****ds back over, and over, and over or report the number to some kind of authority to deal with the situation.

Received call today from this #.. I did not ans. and I have never seen this # before.. looked kinda funny.. 303-303-0303.. looked up areacode which says Colo.  Will not waste my time or cell min..to ans phone # I do not know.  Glad this site is here..

I have got two phone call from this number I do not answer and they do not leave a message.

I got several calls from this number during last few days. When I answer the phone, he hung up.

got a call from this number and when I answered a woman asked for me by name. When I said that it was me she hung up. When I called the number back I got a recording that said my call could not be completed as dialed.

RAng several times.  When I answered they hung up.  No message left.  Been on do not call list for years.

no message left

I have gotten calls from this number a couple of times now. I want it to stop!!!!!!

when you pay good money for phone service. no one should be able to call you from a non existent phone number. I DONT CARE WHO IT IS IT IS WRONG!!!!!!!!!!!!!

Same thing going on with me. I am also on a do not cll list and they've called me about 6 times already since Monday. It got really aggrevating because I'm at work and they never left a message. I called back 2x and it sais I have reached a none working number. I finally picked up yesterday thinking it was a call from my family overseas and this lady sais "hello", I said "hello" back and then just hung up so I didn't waste me time. I hope they stop calling me already. It's sooooo AGGREVATING!!!!

a woman was on the phone when I finally answered this call (I have been in school the first 5 times they called). she asked for me specifically and I said "this is." she said her name was brittany from North American Marketing or something like that and asked if I had requested information about working from home. I said "no," and asked if they would please stop calling me. She very rudely said, "nope, we'll continue contacting you," LAUGHED at me and hung up. I called back and all I get is the busy signal. I'm on the do not call list and have been for some time. I just re-signed up again a few days ago. I am calling the non- emergency police number and reporting harassment since the number seems to be fake and it is outrageous the hours they are contacting me at.

This number calls my cell phone 3 to 4 times a day. I answered one time and they asked to speak to me and then hung up on me. I want them to stop calling me.

They called looking for my wife.  After a delay of about 5 secs, a woman got on the phone asking for her and when I insisted on knowing who she was and why she was calling, she hung up.  Really creepy feeling with this call.  I will contact the police if they call again.

They call several times a day.  No one is ever there.  They never leave a message when voice mail answers.  And I never answer.

keep calling me and when I answer it they hang up. I waited and some guy said something about hanging up and i tried returning the phone call and it says disconnected. I really want these people to quit calling me.

asked to speak to 'me', and I said,"Speaking."  They hung up.

They have been calling my cell phone every day at different times for the past 2 weeks! I never answer...why should I use my minutes for these morons.
