i got a call the other day from a bloke who seemed to know everything about my mobile phone contract.i presumed-by the way he introduced himself-that he was from my "provider"(or whatever you call them).He even managed to get the first four digits of my visa card out of me....i'm usually very aware but I really did think he was from my phone company.Anyway,at the end of the call,he asked me for all my card details.This is when the alarm bells started ringing as I wasn't keen on giving them out over the phone.Turned out this is a company who offer better deals to people whose contracts are almost up.I told him-after he'd tried and tried to persuade me that this "offer"was only open up until the end of that day-that I wanted to talk it over with my hubbie first.Now,he was probably for real but I am a little wary.Anyone else had this?
