After Contract Service

Basically my contract ended end of October 2014. But I'm Still being billed...After more than 5 months? And now that my contract has ended. I'm being billed numerous times a month with different amounts being deducted. I've blocked accounts numerous times, they somehow still manage to get through to my account, apparently certain Creditors/Debtors have this power? ***? I've sent through numerous Bank Statements and e-mailed endless enquiries....and their return e-mailing policy after 3 or 5 working days is utter ********. I don't want to go into the actual gym issues in itself.....and reason for not renewing...but was basically filthy and pathetic in it's own right. But......yaaah, This was a good venting session! F you Planet Fitness seriously! I have not experienced incompetency of this magnitude my whole adult life.....which is +/- 20 years!
