Don't sign up with Planet fitness !

I have been trying to sort out a new contract with planet fitness. The sales advisor quoted me one amount and now Planet fitness is deducting R300 more. I started with logging this complaint on the 9th January, I sent an email where it states it can take up to 72 hours for a response, that was on the 13th of January. It's been 264 hours. Every time I call I am told that a manager will phone me back and no one calls me back. Today I asked to speak to someone senior and the consultant was not able to do this. How is this possible? Surely there are team managers or managers around? I have asked them to either cancel my membership as I was given the incorrect information or to move me from a mega club to a smaller one. I just cannot afford to pay more than what I was originally quoted.
