Horrible service from day 1

I joined planet fitness in April, when they had to debit the 1st premium they debited the wrong account which I had communicated with them prior and gave them the correct details, I filled the form at the gym and sent it to the call center but still my details were not updated. I had to swipe my card at the gym for that month so my membership doesn’t get suspended. Now this month my details are updated but they double debited me why?? Now I’m being charged bank fees for a returned debit order where else they were supposed to only debit one premium as I have already paid the previous fee at the gym. The call center isn’t getting back to me and I need my bank fees back coz they were not supposed to have debited my account twice.
