02135371000

Two calls received over two days - no-one answers at the other end. The first call was from 0002135371000 and the second 02135371000. I suspect it may be linked to a market research call I took a couple of days ago. Has anyone else had a market research call recently?

Just had a call from this number, there was somebody on the other end they knew my name but when i confirmed they were talking to the correct person they hungup!

Rang today nobody there. Have saved the number in my phone with the name 'ignore' so I'll do just that when they ring ........ or I may keep a whistle by the phone >:-(

severeal of these calls, no one at the end of the line. Try to ring back number not recognised!!!

rang a few time today but say nothing

I have had numerous calls from this number - no message ever left.

Several calls today with no response.
Had several over the past few weeks.
Ringing 1471 gives number 02135371000. Number not recognised when called back.

Called me again, i can confirm that it is a Market research company. They asked many questions the usual rubbish - date of renewal of insurance's, do you have conservatory and are you interested in blinds, are you interested in changing energy supplier, have you had an accident in last 2 years ...... Etc,etc.... All questions sponsored by different companies - Thomas sanderson, Scottish power and many others.

Failed to catch company name..... Hopefully won't hear not from them.

Who is this nuisance?

I have received several calls from this number - 24 March/30 March/31 March and many more before that.

I just had a call from this number today, they wanted to talk to me about gas and electricity suppliers. The caller was very polite, but still didn't tell me who they were.

Just had the silent call treatment from this number.  nobody on the end of the line when I answered and would not accept a call when I ranh back.  dated 4 April 2010.

Recieve nuisance calls from 02135 371000 fed up !!! about time someone with some guts fathomed out how stop these calls!!!!!

called twice today, not answered, or called back

just reported then to ofcom  its about time they done something about them

They have called me from 02135371000 for the past 4 days, approx 3/4 times per day. I can only be thankful this isn't my night shift week or else I'd be a lot more angry than I currently am. I am TPS registered so have just reported this number to ofcom.

I'm getting 2 or 3 calls a day - some whilst we're out, they never leave a message but I can see number in list.

When I answered once by mistake I asked for the name of the company - refused. Asked to speak to manager & they hung up

i am sick to death of this number ring now. it has been everyday for 2 weeks. up to 6 calls per day,as late as 11.15pm. most calls silent.last week spoke to a male telling him i wanted to speak to a manager as i wanted my number removing and just hung up. calls continue coming. i have caller id and the number comes up on that,but when i do 1471 it says number not available.Today the number didn't come up on my phone and when i answered it was an asian woman trying to sell life insurance. i told her i was sick of this number ringing and wanted it removed again and hung up on me mid sentence.i am a shift worker and always when im trying to catch up on sleep the phone is going and is them.wish it would stop!!!

Just had my first and last call from this number, with my landline rental (with talktalk) I pay about £3 to be able to block numbers so that they never ring the phone again, just call a short 5 digit number, it tells you the last number that called and tells you to press the * key twice, then its blocked, VERY ADVISABLE!!!! Sod you dodgy foreign call centre, talk to the hand!
