account

I phoned in on the 13th of October to stop my service with dstv. I was told that I can only be disconnected on the 24th because my account was paid till 24th of October. a scheduled disconnect was loaded. I was disconnected on the 24th meaning I have no outstanding balance with dstv. yesterday I got a threatening sms saying I still have to pay 638 or they will take legal action. when I phoned them I was told that payment was reversed on the 7th of October. when I enquire about this how it is possible seeing I owned noting on the 13th and pay cash , a was put on hold and could hear people talking and was disconnected twice. this is not on and if this is not sorted I will take legal steps. this is the reason why I cancelled.
