Lack of communication

I have been with Planet Fitness for a year now. When I signed up they never gave me a copy or sent me a copy of my contract. My membership went through a price adjustment of 10% which I don't have a problem with, beginning of July. The problem I have there was no courtesy notification to remind me that the price is going up with the new price. We all live according to a budget and with that said I make sure that my bank has enough money to cover all debts. With the price that went up and me not being reminded, the debit order was rejected due to insufficient funds, please note that my membership was R648 and there was R658 available they tried to deduct R702. Due to this, I had to pay a bank fee of R7. Friday, Planet Fitness gave me a call and advised me of the problem and that I need to pay R722, R702 for membership, and R20 for their bank fees. I see this as very unfair that I must pay my bank charges and theirs due to lack of communication from Planet Fitness and as I explained to the lady, how can any other company inform their customers of price renewals and Planet Fitness just doesn't care? She was supposed to get her manager to contact me but still no contact.
