Exact was using my account in vain

I have opened an account with Exact. since last year March 2015, the bill of my account was increasing each an every month. i went to the shop in Mabopane to complain and they told me that there is nothing they can do without a statement. on the 15 of February 2016 i contacted the customer care in Cape Town regarding the proble, i spoke to a consultant Mellisa and she told me that the Sports Club Magazine are deducting R26-00 from my account since 2015 March and she promised to make the reversal of 12 months billed starting from March 2015 till March 2016 within 6 weeks. during March when i contacted the customer care to my surprises they told me that an inquiry has been done but there is no response from sports club magazine and they will refund me R30-00 from their side and unfortunately Mellissa is no longer working in their department. till to date the bill of my account is increasing and the exact credit solutions are demanding money.
