I am with Chewbacca - wind the b*****s up.
If it's about a supposed car accident I start discussing my "head injury" - they get very excited right up to the point when I reveal that my head injury has caused complete memory loss because I can't remember any car accident and that must be really bad so they must be able to get me thousands right?
The girl from the well documented nuisance call centre in Swansea (I recognised the accent), was soon back tracking when she called me to tell me I was due thousands in refunded PPI and I started jumping up and down shouting whoopee and demanding to know when she was sending the cheque out. Suddenly it was that I could maybe, possibly, potentially be in line for a refund, that might not be in the thousands.
Indian call centres, are my favourite. When they open with stating their name is David, Stephen etc I always ask them for their real name, the one their families call them when they go home.
I had one persistent man re the Microsoft scam who thought he was on to a winner when I put on my confused old lady act. I even told him I wasn't sure if I had a computer at one point - he still persisted and when he mentioned Windows I said "yes I've got windows" at which point he asked me to turn my computer on. I told him my windows were not computerised - they were top of the range uPVC, double glazed, all with locks, but I had to operate them manually. I thought he would have twigged at that point, but he obviously thought I was someone vulnerable that he could take advantage of. The call went on for ages, with my son rolling around on the floor in tears of laughter - at least while I was wasting the scammers time he wasn't targeting someone else.
