I too have had this phone call ealier today. When I said I was on TPS they said it doesn't apply to them to follow uk law or rules as they are in america. Typical americans thinking they can do what they like when it comes to other countries.
BT or whoever can stop this type of call need to get their fingers from up their bottoms and sort it out ASAP!!
I too received a call from this number a minute ago. It was an automates scam call, pretending to be from a accident compensation firm trying to get you to press number five on keypad.
