Disgusting Customer Service

I an so disappointed in the Customer service i have received, this has been going on for 3 months now, 1st the double debit me for something i didnt renew, then when i return the debit the phone me and tell me its a mistake they owe me, the next month they double debit me i return the debit, a lady from the accounts department calls me and says she will look into it and call me back, last month they triple debit me, i return the debit, todate no one has ever called me back, this is disgusting customer service
