Dstv rewards vouchers 725192

Dstv rewards in my opinion us a **** as when one complains the account gets escalated when they can't fix it. I was told to wait 48hours and it's almost a week ago and now they tell me that I did not respond in 48 hours. Meanwhile I have a paper trail of communication. I played dstv rewards and had a Checkers R100 voucher and combined it with my partners R100 voucher and went to Checkers. The one went through and the second one did not go through and said it was used. It was not as we both hot it on the previous evening. Another voucher after this was for R75.00 also for Checkers. After trying to retrieve the voucher on the site it suddenly froze and I can still not get in. The transaction list freezes so one cannot view the voucher.number. I was told via email it was sent to technically be sorted. I have sent numerous email and it's reached a dead end. I will gladly forward all email if someone would be will to sort this out. There are 2 voucher outstanding one for R100 and one for R75. Leaves a bad taste in my mouth.
