Unjustified over deduction

I requested a change from Parklands red to canal walk virgin active I was told I would receive a email with a quote that I need to accept and then the change will be made, I waited weeks, no email, when I asked the consultant in the gym he said that he would follow up and have it sent, till this Day no email, this morning R720 was debated from my acc, I normally pay R300, I did not approve this deduction, this was never discussed with me, I still haven't received a email of new fees since requesting a change and I was still not informed if my membership was changes, horrible e horrible service, to take money from someone without there knowledge and never giving them the most basic of service.
