02135371000

Keep getting calls from this number and when answered nobody there and then they hang up - very irritating when waiting for important business calls

I've had the same as everyone else, silence then the phone goes dead, rang 1471 the first call was 000213571000, the next was 02135371000
These call started 8th march 2010 at 1536 then again at 1852,
During Feb I got silent calls from 01625870610 evey day up to 5 times reported.

had a phone call from them earlier today, asking for my brother (my dad had answered) and asked what it was about, they said a survey, and my dad said that we didn't want to take part, but they persisted in starting to ask the questions. Dad said "did you not hear what I said"

They also rang AGAIN there now, and I had to do the same thing, you rang earlier we dont want to take part, and the girl on the phone was saying "oh its only a few yes or no's" and you're like...well I don't want to!

They're very annoying, as they dont care whether you want to take part or not, just pester you! Also with TPS so just logged a complaint with them

Just had a silent call from this number. Sounded like there was some one there, but then click and nothing. I'm on the TPS.

This caller 02135371000 calls regularly but never speaks and hangs up.

Keep ringing me but dont speak when i answer it!!  so annoying.

It is a pity that companies (assuming they are a company) like this are allowed to harass people in this way.
I have had three calls today, and as I have caller display, could see the number that was calling and that they have used variations of their number.  02135371000  and 0002135371000.  Can the powers that be, or even the phone company not pull the plug on these type of callers?

I answer the call.  No-one on line

again no one answering on the other end of the line!!!!!!!!!!!!

My wife just answered one of these and 1471 gave the number as 02135371000. I told her that 02 calls come from London area but, to my surprise, when I did a Google search I got replies that say that the calls come from India.
Has anyone ever spoken to the caller from 02135371000?

18 March 2010 - Had a call at midday today - no message - just silence.  Very annoying

This number showed on my phone's Caller ID about twenty minutes ago, but was silent and didn't leave a message.
N.B. Just had another call from this number in the middle of typing the above!

This number have been calling 2-3 times a day and when answered there is no response from them..I'm with TPS but they are no use for silent calls..Many thanks for Mario for the link to Ofcom

I had a call yesterday and today from this number with an Indian saying it was about fuel and wanted me to take part in a survey.I have also had calls from 001323888121 and 0014108852. I have written to my MP who is looking into it.

Wish they would at least say who the heck theyare. Fed up of answering the phone and no-one is there

Caller rang then quickly hang up

Just called, no answer, just silence

Forgot to say, but they knew my full name on the one occasion when somebody spoke, but she would NOT tell what the call was about

They call and hang up the phone once you answer. 24/03/10
I heard background noise of a call centre :l
