Poor service

I've had such a horrible experience from day 1. First I could not log in and that took a month to correct. I went to the spa and had a good experience so I chose to pay everything I owe on cash and continue with the membership. To my horror they keep deducting an additional R200 every month. Im being charged by my bank to reverse that debit and then they charge me ontop of that R200 for them not getting it??? Last month I was told the R200 is for an admin fee so I paid it. This month I'm told it's for the returned debit (even though I settled them in cash) I was never advised of any extra R200. This month again, and now I'm.told I just keep to pay the R200 because they will taking it from my bank? This people refuse to cancel my membership...and now I'm told I will have to pay a double payment ontop of that R200 because its December???
