DSTV lost my payment and now wants me to pay again

Paid R699 for the DSTV streaming option on Sunday 7 July via their website, money came off my account and I was able to watch the full service for one whole day. Monday however I could not as DSTV suddenly could not find my payment and needed me to send them a POP. As the payment was off their site I had no record other than a stamped PDF bank statement that I send through, however this was not good enough. I then drove to PayU (their third party payment processor), some to a man ager and obtained the proof of the payment that I then emailed to DSTV and I am still waiting for a reply even though a ref number was sent and over 2 hours of calls later. Please can you guys sort this out and make it easier for future customers by accepting a bank stamped PDF...I mean what can be any better proof than that??
