Passing the buck. Unauthorized debit order due to greed

Went to Gym Company in Flora Centre for a tour a couple of months ago. Kelvin Audrey gave the tour, told us that there are very few vip memberships available (50 in the country), we said we're not ready to join the gym yet due to personal reasons. He agreed and said that to make things convenient for us when we are ready to join, we should give him our details and our account will be kept inactive until we're ready to join. Two months later I got an sms that my account is overdue. I called and spoke to a very rude lady who said that I owed because I agreed to the contract. I said no I didn't and told her what happened. She rudely responded saying well I need to speak to Kelvin as she doesn't know what our arrangement was and as far as she's concerned I owe. Thereafter I spoke to Duncan on the phone and he advised me to come in. I went in last week and spoke to Kelvin who said he will arrange for my contract to be cancelled with Duncan. Duncan than took me to a room for cancellation and told the consultant to cancel the contract with no payments. The consultant (Natasha) than proceeded to tell me that should I cancel I would have a cancellation fee of over R2000. I asked her if she didn't hear what Duncan just said and she acted confused. Duncan than came in and said that he would contact IT to clear the contract to date and I can continue with the contract going forward. I agreed as I am now ready to join. Duncan than said he would call me within 24 hours to confirm all information. 2 days later I got another overdue message. Called Duncan yesterday and he told me he can't speak. I have never experienced such unprofessionalism and I just want this contract cancelled. I refuse to join a gym where even the reception area on my way out, was unorganized and many customers screaming complaints while the staff responded saying it's not their problem.
