Billed for 3 months for a service I could not use

So I signed up for the Ster-kinekor fan club at R249 PM , which apparently gives you 4 movie tickets , discounts on snacks and only available at specific centres , so I went to Ster-kinekor Eastgate to go watch a movie with my kids , expecting to get four tickets and discounts on snacks , I obviously tried it online to beat the queues but it kept on giving me the full amount on tickets , I then joined the long Q to be told that I need to do it myself online, I stood aside and tried it again , which still gave me full amounts on all tickets , I went back to the girl that could not assist me the 1st time to tell her I’m struggling, she then directed me to the manager’s office upstairs , who logged into my profile on his PC , which showed the discounted amount but he could not continue with the purchase and asked me to try again, At that time I had ran out of data , so I thanked him, went back downstairs to my family , bought data on my phone and tried again , same issue... So I went back to him, but he was no longer in his office , and I went back to the girl that directed him to me , to tell her I’m still having the same issue , she then said the time I’m trying to book for is now sold out and I should try another time slot, with was at late at night. Unfortunately, I could not stay that long at the mall with kids , to watch a late night movie and leave late , so we left and we watched a movie the NuMetro instead. The following month came, R249 came off my account, tried the same process , this time without unnecessarily tagging my kids along , and guess what … same issue. I then emailed Ster-kinekor , and told them my whole story, no response… Month 3 came, R249 came off my account ,I called the service line, rang with no answer and I emailed Ster-kinekor again , asking for a cancellation and refund since I have been struggling to use their services and R747 has been taken from me , which is honestly not fair . Spoke to Kyle Fallie , the Guest Experience Manager who advised that they agreed to a refund of R498 (How so ? No explanation provided) and it will take 24-48 hours, Its been 2 weeks , I’ve been sending follow-up emails , no response from Kyle or anybody else from Ster-kinekor.
