I've been getting this too, I'm also with T-Mobile. It's incredibly annoying! Answered before and just got silent. Haven't answered since. Was freaking me out a little, until I saw this. Cheers.

It is T-Mobile.
They just called me 3 times in 15 mins, at the 3rd time I picked up - very annoyed. They wanted of course to sell a promotion, I answered very harshly "I am busy and have no time". The guy tried to instist but I cut short just shouting to stop calling me, then hung up on his nose.
Very easy and effective: tell them to F*** off and they wont bother you again!
Do not let the phone ring as they will keep calling until you answer, just tell them to go the hell and the business is over in 3 secs.
Bloody company.

called me 3 times today! and this is not the only 0845 number that has been calling me recently! am seriously getting fed up with it! surely if you dont pick up so many times they would get the hint that you dont want them calling you!?

I've had this number call me twice every day for the last three days- I have ignored it but glad I decided to google it. Why are T-Mobile doing this? It is so annoying. I'm going to change companies! Was in two minds but this had made my decision final!

this number has called me 4 times already today. i had a different 't-mobile' number calling me every day for about 2weeks which i just ignored, and now this number is doing the same!
is getting rather irritating...especially when they don't speak and just hang up when you acutally answer!

This number has called me persistently for 3 weeks. It's T-mobile. they use 08454123104 as well.

When I pick it up there is no-one there, or presumably I am not prepared to wait long enough for them to route me to the next available operator... too right!!
They call when I am at work and can't take calls but seemingly, my not answering the 'phone is not evidence enough for them that I do not wish to speak to them and they call three or four times one after the other on each occasion.

I rang customer services who were able tell me that there were no problems, I was nt eligible to upgrade my 'phone, and that it might just be a courtesy call to discuss their current offer on broadband?  Silly me, I thought if I wanted broadband I could call and ask for it!

If you think I sound annoyed you are right and like a lot of others on this site it seems and deteemined that if they call again I will report it to whoever it takes to make it stop!

Same for me (also with T Mobile) - hangs up when I answer. Very irritating, and hopefully I will be able to get a human on the line to let them know how I feel about it!

They Have called about 5 times now evrytime they hang up and this morning they worke me! :@ was not happy!

number has called me 2 times before, but 2day theyve called  3/4 times! i dont bother answering it but its IRRITATING!!

Had this number call me twice whilst I was abroad!! Not good!! And there is no one there which is infuriating!!

No-one there

3 missed calls from this number

I have just had two calls from this number and so I googled the number and found this website. I will be ignoring any future calls! thanks

Call from 08454122750 but line stays silent when answered

Just had 2 missed calls from this number within a matter of minutes of each other.  I called it back from my work phone and it said 'you received a call from T Mobile you do not need to take any further action..'!  I am a TMobile customer, no doubt they will ring again

Just to add to above......they just called again and were tyring to offer me mobile broadband.

Just had 3 calls in 10 minutes. Rejected all of them. If it is that important, leave a god damn message or stop ringing me!!!

Got rang 21 times yesterday by this number.
I just kept answering and not saying a word. They were getting very very frustration -literally shouting HELLO! HELLO! IS ANYONE THERE!

I'm glad to have pi**ed them off. They have been annoying me for months.

Just had 3 phone calls. Missed the first two.  Lady trying to flog something for T Mobile.  When said not interested was very polite and conversation ended.  Hopefully this will be the last of it.  Will let you know if not.

Have been called a number of times on this number but no one on the end of the line then hang up. Do you get charged for this?
