I am very very disgusted with DSTV

Good Day My DSTV Dish has been off for a while and I paid the amount that DSTV (Multichoice) gave me on Whatsapp plus reconnection fee. A month later I then made another payment as a monthly subscription fee. When I enquired two months after that on whatsapp my outstanding balance was now my monthly subscription and a reconnection fee. I enquired from their call centre and was informed that it was because the payment I made two months after the last reconnection was because I paid a day later than my agreed date. I advised them that that my payment date was not the 1st of the month as they claimed it to be and also my dish was never disconnected on the 1st of the month as they claimed it to be my payment. So why are they billing me with a reconnection fee when they have never disconnected my services
