I've just had no less than 6 apparent scam calls (answered), one after the other, from 020 8044 4164. The first, seemed to be claiming to be from O2, simply replied that it was a scam and not to ring me, and put the phone down. seconds later, another call from the same number, different person(both Indian), who got some of the same, then the first person rang back quite annoyed I had put the phone down on him. My own reply by now very annoyed. Those followed by yet three more calls, all quite aggressive.
Ringing the number back, it showed as a none existent number. Searching on line, nothing matched it.
