DSTV disconnecting my services after making payment.

DSTV/multichoice keeps disconnecting my services. I have made an early payment on 23 January 2020 in which payment was only due on 2 February 2020. DSTV then disconnected my services saying that my payment was not allocated property. I then proceeded to send the proof of payment to them. they reconnected my services, however, my services are disconnected on a weekly basis. I have to call them every week to explain the same story for about 20 minutes each time. Every consultant assures me that they have allocated the payment and i should not have this problem in the future. This is extremely irritating and such an inconvenience. I Really do not know who to complain to anymore as managers comes up with the same excuse!!!
