BAD service, lies and misrepresentation

I have been a loyal member of Planet Fitness for three years now. I renewed my contract at the end of February last year (2014) and paid upfront for 12 months (ending end of Feb 2015). One morning upon arriving at the gym for my usual early morning work out, I was denied access to enter the gym as I was told that I was in arrears. I proceeded to tell the receptionist that this cannot be the case as I paid for my membership a year in advance. I was told that I also have to pay a club levy (despite not having been a member for a year yet). I raised this concern with the club manager and was told that it would be sorted and the charge reversed (as I had no obligation to pay the levy since I had not been a member for a year yet). Three days later I was given access to the gym again. On 23 Feb 2015, I decided to call to enquire about my contract and I was told that I owed the club a levy of R299 pertaining to December 2014 and if I didn't pay at the end of this month that I would be given over to debt collectors. I have never received any communication of this before and I was outraged. I want to cancel my contract and have this \levy debt"cancelled. I will NEVER use PF again!!! """
