Poor customer service

I have a Value-Added Service (Scratch and dent cover) with Dial Direct. I noticed that my payment is not being deducted for two months. When I called I was told that they haven’t received the payment. Someone in that company changed my payment details to my husbands without our consent and as far as I know it’s against the law to use someone’s details without their consent

I have been trying to resolve the issue with the staff but I am not winning and on Monday 16th I called again the line disconnected or dropped and no one called me back

I am really disappointed on the service I received for the past few weeks been a valuable customer for 4 years
