Problem on account not solved

Since August 2015 I encountered a problem on my DSTV payments. Multichoice do not allocate payments made on my account. Every week I spend time at the agency to try and fix the problem. After sending e-mail after e-mail nothing has been done to solve the problem. I sent them proof of payments as well as a bank statement of payment stamped by the bank. Every week my DSTV gets suspended and when reconnecting they add R50.00 for connection fee. Why is it taking nearly 4 months and still nothing is done?Is it because they have enough clients and don't care about the ones with problems?
