Horrible service

I made two payments to my dstv account by mistake .fist one was made on the 27 October 2020 and the second one on the 2nd November 2020.when I called them a week ago they said its reflecting on the statement and I requested that they refund the one payment made on the 2nd of November , till now I haven't received my money, they keep on telling me that they want proof of payment .I sent them the statement and highlighted but they still came back ask9ing for proof of payment.

I find it very annoying that they are too quick to deactivate once account if no payment is received but the minute they have to pay you back they come with stories. I want my money back as in now
