Horrible experience with Planet Fitness!

I joined the planet fitness in Olympus a year ago. It has been one disastrous experience. My first installments went off without my vitality benefit linked to my account even after ensuring this was done when I app****. The gym has no air cons. The service is utterly poor. Rude customer service when phoning to cancel after a year wasted cause it is impossible to gym with the high volumes of people and no air cons... Impossible to get my membership cancelled. Once it was cancelled the full amount of R899 went off again twice. What must one do to never hear from this company again??
