DSTV Not Being Able to Reconcile My Account

I do not get what DSTV is trying to do and if they cannot solve a simple accounts problem then I rest my case.

So the story goes as follows. On the 26th of March I had an additional decoder installed at my moms place (bought with free installation and one month free compact viewing). Since lockdown was beginning on the 27th of March,I decided to go to my moms place and left my house where I do have another decoder on compact subscription. I had already paid my one for the month of March and knowing that it was lockdown and I wont be at my house but my moms house I decided I wouldnt pay for April as I wont be at home. As they do they disconnected mine and I was okay with it because I was at my moms place where I had just installed the new decoder with free sub until April 26th. I had to come back to my p;lace on the 2nd of May and as usual I would pay for May and the extra 3 or 4 days of grace given by dstv before they cut the services off...so I got home,my decoder was not working and I decided to go online so I could make payment for my decorder and to my surprise my account is siting on R1500...till date no one can give me a valid reason apart from the fact that the 1 month promised as free was not free and was billed on my account and now my whole account is a mess and there are so many charges that dont make sense. If this is what dstv does with pep cell to take money falsely from their customers then it wont happen with me. I will not take this, I have been in contact with dtsv online agents and they cannot explain it to me,last night I wrote officially o the dstv help email address and I received a responds from Elizabeth who is basically telling me that DSTV took the R399 discount and allocated it to my DSTV so i need to pay it. What am I paying for as when I got back to my house my services where disconnected and I wanted to pay for May since I was back at my house. The last time I checked DSTV was pay as you go and if you cannot pay for a certain month you dont pay and they disconnect your services...Why am I being de*****ed?

I eventually paid R550 for my compact R399 plus insurance R20 plus my moms Access R110 which I downgraded as she said she did not need all the channels. I then contacted the online agent who told me to pay and extra R285 for the extra 3 to 4 days of viewing and R50 for reconnection. Now every 3 days i get disconnected and connected and the amount on the statements does not add up and everything is a mess. When I call the call centre for assistance Im told their offline,and there is no accounts email where I can get a proper response. Now my connection as been disconnected and I do not owe DSTV. What is this? Will DSTV credit the days where I cannot watch TV due to this mess or is this how pep & dstv operate by selling products to customers and later making thme pay for what was advertised as free?
