08454122750

I've started having similar calls in last few days...
Has anyone else actually complained to t-mobile about it - surely if everyone who's posted on this site went directly to t-mobile they might take notice and try and do something about it/give us an explanation? I know we can ignore the calls but we shouldn't have to be pestered like this - and I'm sure we should be able to be given the choice to protect our numbers.
I have sent an email to Watchdog!

Had a missed call yesterday. Haven't tried calling back and found this site while searching for who the number belongs to on the net. I am also with T-Mobile

Yip it's T-mobile. They were trying to sell me mobile broadband

been pestered by 08454122750 so much witht he line dead on the other end so they rang me and i answered it and left it on the side to waste them money and a scottish lady was saying hello so ignored them. within 30 seconds a different number rings 08456850048 answered it and it was the same woman so i hung up now im getting rung by different variations of an 0845 number

I had a missed call from 08454122750 at 5.37pm today (24/06/2008) i didnt have my phone next to me at the time, and i NEVER call back any numbers i dont recognize, i am also with T-mobile and have just re-newed my contract within the last 10 days

just got a missed call from them - I didnt answer - decided to post the number on the internet 1st. And i'm glad I did- I have mow preset the number to "DO NOT ANSWER" lol

Got called by this number yesterday just before 6pm.  Missed the first and then 10 mins later they called-I picked up-then it went dead.

Same number just called me again and got a bit suspicious. Am now not going to act on it.

this number calls me every day at about 12:30pm...it's calling again now...

With T-Mobile and get a few phone calls from numbers like this one. All the same rubbish - I just ignore them all but a bit of pain. Very useful to have this website to confirm my beliefs.

Have been getting calls from another number mentioned on this web for a little while, normally around 5pm for several days.  Today at around 3pm got a call from this number 08454122750.  Was out of the room at the time.  I am with T-Mobile too.  I still get loads of calls from O2 because I used to be with them but it's always when I'm either on holiday or busy so I just say "I'm busy" and never get round to saying "I'M NOT EVEN WITH YOU - LEAVE ME ALONE!"

Tryed calling as annonymous before but now changed to the displayed number

also with t-mobile.  its phoned me 5 times in last half hour but not left a message either time.  I suspect thst they put it on automatic call back but if they are busy with someone when you eventually answer they give the engaged tone.  Such a bad way to do business.  Certainly will not be picking up as my other suspecion is that it might be some sort of hacking thing to get into your phone.

Thank the lord above for this site!

I missed my first call from this number today and after finding this site will definately be avoiding taking calls from the number...
Last year I kept getting calls from "T-mobile", but always at an inconvenient time (when driving, when overseas on holiday and even while I was getting dressed for my wedding!) Finally after a couple of months of calls, I agreed to listen to their upgrade offers. The next I went to a TMobile shop and spoke to the shop assistant, we found out I wasn't due for an upgrade yet. Next time they rang I found out they weren't actually from TMobile (as they had originally claimed) but from the shop where I had bought my phone...

Just the two calls for me, about a week apart - looks like I've had it easy compared to some. Never answer them, and surprise surprise, I'm on T-Mobile.

Wow! Looks like I'm not the only one T-mobile's been pestering- they've been calling me as late as 20:45!

I stopped answering after having to deal with very pushy people, trying to get me to agree to various offers- and before I know it I've spent ten minutes on the phone and one step from confirming some kind of offer!

Once I told them that I didn't want to commit to something at the spare of the moment and the guy just hung up on me!

I'm one step from cancelling my contract if this persists!

Similarly, 3 calls in the space of 30 mins. I'm eligible for a "free USB dongle" - lucky me!

I've never had any trouble with unwanted calls like this before T-Mobile contacted me for market research a couple of weeks ago.

Yeah as above, T-Mobile trying to sell mobile broadband.

Yup - its a T Mobile number. I called back and the announcement said "you have received a call from T Mobile. You do not have to take any action as a result of this call".

Nice folks eh? I just Lurve silent calls - not!

yea tmobile here to, 3 calls in 30mins... really annoying =/

they have callled 4 times in the past half an hour:|
and also another number "08448849172". Doing my box in
