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!!
Just got the same call at 16:10. Waiting for the announcement and pressed 5 to speak to an advisor. Spoke to male with an American accent claiming his company name as "UK Consolidation". Doubled checked this and said I wanted to make sure I had it right because I'm registered with TPS and should not get these calls. When I said I needed to report this to the authorities, he put the phone down.
