Highly furious

I'm so disappointed with Tyrone from liberty mall planet fitness, sold me something else and made me sign another. I was told to activate a false discount' that I was supposed to pay R374 and right now they debted R499x 2. I called him making him aware of what was happening he gave me the head office number, when I'm calling him back he is not answering my calls anymore. I'll reverse my money and should planet fitness hand me over who's fault is it. He made my Coloured colleague sign the right thing, I don't know whether it was a race thing or what
