After finally getting rid of BT, I thought (hoped) it would be an end of it but no. They continued to call me trying to sell me their services despite the fact that I had opted out and I was a member of TPS.
When I told the caller this he laughed and said “we are BT, we are exempt”. I made a complaint and eventually got someone to take it seriously but they never called back to say what they had done about it (they said they would).
BT have also broken the law on Data Protection, they continue to send me unsolicited email despite my efforts to opt out, the unsubscribe link just opens up an email and when you write to this you get a message saying it was not deliverable. They deleted the mail box.
I called the BT head office and they will not put you though to anyone unless you know the name. So if you ask for the Data Controller which they are obliged to have under the data protection act, they refuse to put you through.
All I can say is DON’T EVER BUY FROM BT !
