DSTV MULTICHOICE

Good day On the 4th of January 2020 i went to pick n pay express at Diepkloof BP garage to pay my DSTV an amount of R650 i was helped and my payment went through. Then on the 24th of January 2020 my Dstv account was closed because they had said i havent paid. I then contacted DSTV to find out why they said so, i was told by a customer service agent that sumeone had called in that day and told them that he or she made payment on my account which was wrong and they then had to remove the money i had paid and put it in their DSTV account. Im still disconected till today they say there is nothing they can do even though they see the payment that i made on the 4th of January 2020. I dont know what to do anymore and i feel that DSTV Multichoice has ****** me,may sumeone please assist me on this matter as i dont understand why they would let sumone tell them to disconnect me because they have paid in my account if that was the case then it means my account would have two payments not one. Please help
