Unauthorised debit orders

I signed up for a one-year contract in February 2014 and paid up the entire annual fee in full at the beginning of the contract and told the salesperson (name tag Sandra) that I did not want to renew the contract at the end of the year. Despite very clear instructions, Sandra **** and marked my contract for automatic renewal, although, thankfully, the contract is marked NA in the column where the renewal amount should be entered. At the end of the contract period, Planet Fitness took almost ZAR 900 out of my account, with no authorisation and attempted over and over to take money from my account. I had to pay bank fees for each unauthorised and unsuccessful attempt. Planet Fitness has not responded to my letter to them. I will certainly never take a membership with them again and I have also lodged a complain with the National Consumer Complaints forum. STAY AWAY from Planet Fitness - they lie and cheat.
