08454122700

No idea who this is.  It rang several times but rang off before I got to the 'phone and didn't leave a voicemail message

Just blocked them. thank you iOS 7 :-)

Get calls from this number a lot already had 3 this week. I have never answered as I do not answer numbers I don't recognise and if its important then they can leave a message. This number never leaves a message. I am not due for an upgrade so its some kind of scam so my advice would be to ignore these calls.

Thanks for the info people, had 2 missed calls. Will be adding this number to my rejection list as it is obviously a scam of some sort.
Probably just some scam artist pretending to be T-Mobile/ EE rather than being from the telecoms company.

Stay sharp folks we will never stop parasite cretins but we can stop them living off us. Unless you recognise a number that calls you and it starts with 0845 or something similar don't call it back. If it's an honest call for you they will call again.

I keep I have received two calls from this number I'm hoping to hear from an employer about a new job and querying whether this was them is there anyway to find out?

This number is constantly calling me.  From the comments I have read on here I do not answer it.  They never leave a message on the ansaphone, just keep ringing.

they called me and i dont even have a contract phone

Much the same experience as previous posts. T-Mobile, Orange etc. I'm really sick of these anonymous numbers...!

called several times

I got a call from this number and was asked for my full credit card number.
Are they crazy enough to think I would give such details over the phone.
I told them I wouldn't and emailed t-mobile with a complaint.
Still waiting to hear from them!

Its T mobile customer service checking you are happy with service, charges and signal

why the call

I've missed four calls from this caller in the last three hours

My phone is a contract phone and yesterday I called EE to cancel and pay off my contract. Today, I get plagued by this T Mobile number.
I'm sure that's not a coincidence.

Bloody pests

Ditto, I cancelled tmobile yesterday and just got my 1st call from this number.

Coincidence NOT, I think!!!

This is my experience too.  I cancelled my phone contract (a month early) yesterday and also cancelled by mobile data contract and now I'm getting these calls.  I'm disillusioned enough with T-Mobile already so if they think this will make me change my mind they are deluded.

Called on my mobile, but I don't answer numbers I don't recognize.

T-mobile contract is up for renewal but they have been calling me twice a day, very annoying

Called 3 time today did not answer

When are these bloody annoying calls going to stop ??
