Double Billing Shocking Service

After activating my new smart card in July, MultiChoice never deactivated the old smart card. This resulted in my account being double billed for 3 months. After it happened the first time I phoned the call centre and was told that it was rectified and that my account would be credited. The following month it happened again after which I logged an email complaint only for it to happen a third time. On the 2nd of October I phoned the call centre yet again and spoke to Zandile Mhlongo who seemed very helpful. She assured me that the money owed to me would be paid into my account in 40days. As ridiculous as it was that I had to wait that long for the money to be paid back to me I agreed, got my reference number and her email address so I could get hold of her directly. It has now been 8 WEEKS, 56 DAYS and the issue has still not been resolved! I emailed Zandile and have had no response. Customer care at MultiChoice seems to be nonexistent. Every time you phone you speak to a different person, there is no way to get hold of anyone directly other than direct email and even then you get no response and every time you send an email you get a different reference number. Pathetic!!
