well this is what I wondered....and what got my paranoia going but I haven't spoken to this person before like they say we have 'just had a conversation and got cut off.' Surely you would leave your number on an answerphone? if it was a premium number you probably wouldnt check if you just used the 1471/3 service. the way she started by saying 'i believe I am speaking to Huggers Name (mispronounced, so maybe she didnt have that much time to write it down) blah blah' ....sounded very odd, and as I say, the name could have been picked up from the answerphone message, although the number itself doesnt appear in the directory of market cold call spammers, the 0207 450 prefix is a common denominator to all of them. p.s. edited to add, my children are teenagers, where from all paranoia comes.
