Unprofessionalism and second payment deducted

I received an sms saying my May 2015 payment was reversed. I then logged a call with The Gym Company on their website. I received a call back from Michele who was not helpful at all. Firstly she requested i sent my bank statement in which i only sent a part of my statement confirming payment as well as a second payment that was also deducted - she plainly said she has to get my statement but according to the PPI information i don't have to send her my statement. Her response back was plain and simple that it was reversed without any further assistance. This is highly unprofessional and no assistance from her at all that sucks. I have proof on a monthly basis that this R199 plus an additional amount of R198/R199 comes off my account why would i suddenly skip one month. I'm very unhappy with this. I will definitely cancel my contact with them if this carries on. Sies man
