Discovery vitality feature was not communicated

When the sales consultant \sold"the package to me I wasnt told that you can pay R99 if you have a discovery vitality membership. Now I'm trying to get that deal as i was not told about it then they tell me I will have to transfer my membership to someone else then start a new account. Then there's also the issues of late debit orders. I have been pleading with them to change my debit order date to the 25th of every month because that is what i stipulated in my contract but it has been only resolved after months. I am really not happy with this Gym i want to end my membership but there's a fee attached. No wonder they bind you to a contract because they know you will leave them soon in any case. I wouldn't transfer my membership to anyone"
