02031418843

I work for phone companies and it isn't 3 network calling you! it is a scammer trying to get bank details. I have reported it to the network but how far that goes is a different matter, best thing is to keep reporting it to ofcom until they get the message!

This no. been ringing me for the past week, stops if you don't answer quickly. Answered it once to listen to call centre background noise then cut off.
Thanks to this site for information, I never sign up knowingly to receive junk mail/calls & hardly use my mobile- can only think it happened last Christmas when I bought a new pay as you go phone from shop & the kind assistant set it up for me with my own sim card.

7 missed calls in one day. They driving me insane. They've been calling me all week !!

I have been called 4 times today from 02031418843 - getting really annoyed with it now.  Soon as you answer they hang up....

they phone everyday but won't leave a message, very annoying.

Having quite a few calls from this number, called it back a few times from landline, but goes to an automatied "your call is very important to us etc" then eventually a womens voice comes on and says goodbye ! won`t bother calling it again, nor answering my mobile to it !

Called me twice today 10 minutes between calls.They didnt understand I'm not interested

bloody annoying trying to sleep from a nightshift with these clowns phonning at all times of the day;would be nice to find out where the 'office' is eh and go round there and disconnect a few things

Three Mobile - They have called severl times a day for weeks, every other time when i have got to the phone they have hung up. Today however when i answered i got the usual sales talk and when i confirmed that we didnt top up our spare pay as you go phone (with orange) with as much as they wanted to hear they put the phone down on me!!! They had better not call again as i may not be polite in future!

Please stop this [***] calling me

they've called me three times in two days and every time i pick up the phone they hang up. I just called them back, sat on hold for 5 minutes and they then cut me off!!!!!

This number calls me every day

I just got phoned and googled it!!...hoping they wont call back but glad i read all your comments above, thanks everybody!!! xx

had a call from 02031418843 again .. yet again said no thanks , then get some 15 year sounding pervert making sexual comments then hanging up........surley thats not legal!!!!!!

I got calls from this number but they don't leave messages - when I call back there ia a voice telling me that someone will answer shortely that  does not happen just tedious  music.

Don't call them back , this is SPAM, they will charge you something like £5 per minute, place you on hold and you will never get through.

I keep getting calls from this unknown number - I want it to STOP as I wont answer it.

I have been called several times today by this number and then when you answer the phone you end up in a call waiting queue and then nothing.  

What is this number? who is calling?

Received a call, which I answered from this number. I said 'hello' - to no reply. I could hear breathing and noises in the back ground. I said 'hello' once more to nothing ... then a women said 'goodbye' in a rude manner! My boyfriend rang the number back to reach an automated message saying it was the 3 mobile company and all their agents were busy. So rude and quite concerning!

this number rang me and i answered and they said nothing but im glad i googled it, thanks everyone!!
