Services incorrectly stopped

I made a payment of R630 on 25/01/2021 which should be for my subscription up until 25/02/2021 but on 01/02 my Dstv was stopped and I was sent an sms to pay R400. I called the call center and was told some ******* about not having paid for December. I paid on 25/11 for the month of December but I was not home from the 15th. I understood that my viewing would be stopped on 25/12 so I do not understand what I am owing for as I made a payment when I was back home and needing my services to be reinstated. My call was disconnected but the agent never called me back so I did not even get a proper explanation or get to dispute this. I do not have the time to be on the phone calling your call center. Please reinstate my services as this is ****************!!!!
