Box office rental disaster

I rented a Box office movie on Friday last week. Paid with credit card. No movie became available. I went on to live chat, said to operator I rented movie, was then told the credit card option doesn't work, I have to wait until it reflects. By Sunday, I was on live chat with about 3 consultants, no one could help. By Monday, Grace was the second consultant, said I must re rent it on dstv option, which I did, movie was available immediately, after paying R80 for the movie. So Given assisted, and promised in 48hrs the amount will be credited to my account, still waiting for this to happen. So today, Thursday, almost a week later, went on live chat again, got Grace again, and problem still not resolved. After sending proof on many occasions, I fail to understand why the R40 can't be credited to my account. I've spent more than 2 hours of my time on live chat, trying to resolve this R40 issue. None of consultants also assist until resolved, they just send message thanks for contacting live chat when they can't assist anymore. I'm at wits end already. No consultant will give me reference numbers also.
