Worst Customer Service experience

In 2017 I opted in for the dstv price lock and that's where my nightmare began. Every month I had to go fight for my money coz they would debit my bank acc with thousands of rands. I eventually got them to cancel my debit order and give me written confirmation of this. Every month when I go in to make payment I apparently owe them more money than what my actual compact pricelock package is supposed to be. This has been going on for months and every time I got told that I owe them money and I get disconnected. In April I got an SMS stating that my last payment for pricelock is in the 1st of may 2019. Lol and behold I go to make a payment in June for the compact package without price lock and I was told I'm still on price lock. Every month the same story. Apparently I have multiple accounts with dstv but I only ever had one. On the 1st of September 2019 I went in to make a payment of 250 and requested to have my payment date change to the 15th as my pay date changed. I was assured by the lady in the branch that my payment date will be changed and my service won't get disconnected. What a joke. This morning my services got suspended. I called the customer service who was absolutely useless as the woman never left any notes to say that I wanted to change my payment date. I'm so frustrated coz every month I have to go fight as I am constantly over charged. I have to drive to the branch coz their call centre agent are a bunch of robots who do not have any idea how to treat customers. I'm just fed up and that's putting it mildly????????????????
