Incorrect billing that is not being corrected

Good day Dstv agent can you let me know how long it takes to sort out a customers billing after all DSTV made a ***** up of the account. Price lock is a night mare. How I wish that I can cancel my package cause all its caused is a big mess up. The Supervisor at the Call center takes one week to call me back. When he tries to sort the account out of which 50 % completed. It's as if they can't COUNT. Let's not talk about the bad attitudes at the call center. One of the agents actually said to me the customer is not ALWAYS right, and i was shocked. They actually told me that I must listen to them. When I am the one calling with the account query and they don't even want to listen to what I have to say. When u have a price lock package the debit order amounts can't change,only if you rent movies. They changed my price lock on my box office account.... I have spent maybe over R2000 on call the Dstv customer call center. I spend hours on the phone with them. This problem is going o. Since April 2018. I think I have had enough patients with Dstv now. I can even jot the names down of every agent I speak to. I have a few reference numbers that I can also provide you with. So hopefully I will get assistance with my account. Very angry customer....
