Showmax wont help refund me my money

I wanted to upgrade my Showmax and believed I was, I was Downgrading for more money... When I contacted Showmax to assist me in refunding me or changing my subscription on the back end, I get told what subscription I bought and now I am ignored. All I wanted is Showmax on my TV not my phone and it seems they dont care. R99 compared to R225 and they happily take my money and I am not getting any service. All I am asking is for them to refund me the R225 so that I can correct my mistake and get the right subscription. Who else feels R225 is a lot for tv on your phone only, yet R99 for your tv and many devices? I thought I was buying into the Showmax with sport. Seems the joke is on me. Because now I am out R225 and no TV on TV.
