Delinquent Service Provider

I had to pay for double amout on my decoders, due to incapabilty of Multichoice agent. On the 14 09/2020. I called the to reconnect my package due to they have disconnect my decoder. I downgraded to access on the 7/09/2020. The App requires me to pay R249 for all my decoder. But now they are claiming I'm owing them R170 for reconnection. My payment date is 7 of every month. Then why do I have to be charge on the 14 and 16 Sep. For what reason. I think it's time to get a competitor, cause it looks like multichoice is playing with clients. Spoke to Samkeliso, she was rude and end up hanging the phone. I need an explanation. Really I'm very much disappointed.
