Debited my account three times within a few days

The admin of this company is shocking and terrible. I joined the gym on 19 February and paid a pro-rata fee for the month on February immediately on joining. I told the consultant that I agree to my next payment being debited on 1 March but would prefer the next debit order date to be on the 27th of every month starting 27 March 2015. He agreed that payments would be arranged that way. However, my account got debited on 23 February with R385 and again on 28 February for R395! This is not what I asked for or signed for or agreed to! This is terrible service for a new member - how could you get it so wrong? I would like someone to reverse the additional deductions from my account and dare you ask me to fill in any paperwork for a mistake I didn't have any part of making!
