DSTV DISCONNECTED

I paid my dstv on the 31st of December today on the 2nd of January a received an SMS that my services were disconnected due to payment not being done I called their customer centre spoke to one of the consultant and she confirmed that I did make a payment and she doesn't understand why I was disconnected she said she will reconnect me and that her system was slow. The phone cut us off I called again and spoke to another consultant and she said the last payment I did was on the 1st of December. I am sitting here with a decoder that is not working while I paid for it please assist.
