rite ok guys ive just solved the phone number problem. i have been getting quite a few calls from this number. it turned out it was my mum calling from one of those cheaper rate prefix numbers you put in before the number you wish to dial. so this just means we all know sum one who is careful with there money.
;-)

This number is from one of those call centers trying to convince me to rent my holiday property through them. Annoying to say the least!

This seems to be the number displayed on my mobile when my Mum uses a prefix number to get cheaper calls to mobiles
Bit of a pain - would have been better if they could display the originating number but that would probably cost more....

I better check that they really are giving her a good deal.
