Wants money refunded

In December 2015, I got dstv activated, I was told to make a payment via my ebills, I did that, later the month, my subscription was suspended and I was told I did not pay, I made a second payment via my ebills, at the end of the month it was suspended once again, dstv said they never received the money, I went to my bank and the bank said the biller did receive the money and I must claim it back from dstv. I have emailed dstv everyday since and its been a week since I received any response, everytime I must send copies of proof of payment, bank statements and ID, but it doesnt go any further. All I want is the money that was paid, because R768.90 is a lot just to write off. My dstv is paid and up to date, but this money still hasn't been recovered. I am being ignored. Bad bad service from dstv/multichoice.
