Incorrect information provided/lake of service received/staff that lies

We signed our son up at V-CLUB about 2 months ago, we advised the sales consultant that I want to test it out as I was on maternity leave and should it not work then I will cancel the membership. My husband is on a month to month contract , we both asked her can we cancel at anytime and her response was yes. We used the service twice and realised that it wasn't working as I returned to work and gym is next door. We went in and requested to cancel the membership for my son and was told there is a R400 cancellation fee, if we signed the contract we read the t&c, there is no month to month contract , only 12 months. Doctor or Doc was the manager on duty and advised that he will speak to Sandra and call us back. Sandra naturally denied everything. My husband asked Sandra to get Doc (manager) to call us back which he didn't to date, almost 2 weeks later. They have no people s****s whatsoever and just said that if he takes it up to management their first question will be if we signed. Your staff mislead us and made us believe that we can cancel at anytime, please review the footage no one explained anything else to us, it was just sign. My son was irritable on the day as well. Another thing, the condition of the gym is putrid, its dirty, forever leaking, things are always out of order, cleanliness is not a priority....the list is endless. I have some photos, like how the dirty water runs into the pool...its so bad. We should be paying less to nothing to use this facility compared to other branches like 14th Avenue.
