False contracts, overcharging students

I’m so livid at this gym. It exploits students. I was approached by one of their consultants offering me a R99 deal for two years as a student in 2019 December. Well that’s what he said. Only for them to start debiting R370 and some months R600 from my account the following year. After 9 months of the second year I cancelled my subscription and they said I wouldn’t have to pay anything anymore. Close to a year a rude lady calls me and tells me the gym sent me to lawyers and I them R999 and I don’t pay up, my financial reputation will be ruined and I will not find a job. Then they send and email claiming I now owe R1700. The worst gym ever!!!! They make sign for deals that aren’t true and milk you. Now I’m being harassed by their people.
