0203125123

I've received 3 calls from this number throughout today, but I have the new BT Nuisance Call blocker phone - an absolutely brilliant phone - I can block calls on a per number basis but also block with-held, unavailable and international - this number is now added to my blocked list

2 call about 1 hour apart, hope this is not the start of pest calls

Received 5 calls today from 0203125123 and every time the phone goes dead with no one at the other end. Really infuriating and reading other complaints, it's about time something was done!!!

This number rang at 9.05pm tonight. No one on the line. I said who are you, then they hung up
