Deceived by virgen active menlyn

I have been a member of the virgen active group for a long time. I have switched between branches telephonically in the past, no problem. Just a quick adjustment on the computer system. So when i phoned the last time to move to a new branch to move my contract they told me that i can't just renew my contract , i have to physically go in to the gym to do so. Firstly they already had all of my details on the system so the person in charge of sales, earning commission on every new member, obviously did this so that they could earn money instead of someone just altering my membership branch on the computer. There they told me that i cannot go onto a membership that allows me to cancle my contract at any time, that it has to be a year or two year contract. My previous contract at that exact same gym was on a contract that i could cancel the contract at any time with a month's notice. I am not happy with being deceived in order for a company to make money. Previously i had spoken to the head office of virgen active who adviced me to go on a contract which allows me to cancle with a months notice. It was the menlyn branch who told me that this is not a valid option and that there is no such ontract. I also am not happy about being informed that my subscription will go up because of the tax increase. Under no circumstances is a contract allowed to change without both parties agreeing. I do not like being informed that this will change as i gave no concent. I am very unsatisfied with all services from virgen active menlyn branch.
