Extremely bad customer service

Extremely bad customer service. I reported a ***** incident and had to cancel my Card. I was informed that I will receive feedback within 10 working days. More than a month later I spend 20 minutes on hold and being passed from one consultant to another to be informed that the investigation is still underway. The next week I receive an email that there is information outstanding and that they cannot assist me. I have since sent numerous emails & tried to get to a consultant that can assist me unsuccessfully.
