Planet fitness is cheating you out of your money

Having been a member of planet fitness for years I often have problems with them just debiting money’s from my account, when questioned they will always have some sort of a reason behind it. The lates one was that they debit you another months membership for the maintenance of the club. What bull**** is this. I pay to become a member and that money needs to go to maintenance and upkeep of the gym you don’t charge your clients more because you don’t know how to budget. Not just that but they don’t even inform you beforehand.
