HARASSMENT

Supersonic have emailed me more than 5 times and have issued 8 tickets regarding a credit card that they claim has expired. They have also sent me so many sms messages that I have blocked the numbers. It is harrassment. I DO have an account with Supersonic but it is NOT the account number which they are harassing me about. But if they continue and do not respond to a single ticket and do not have the COURTESY to pick up the phone when I have advised them of the correct account number, then I may look for alternatives. So their method of dealing with it is cancelling tickets that are duplicated and responding to NONE.
