Joined as Vitality, debited as Normal Membership

I joined as a Vitality membership which was for R169 per month. Then they are debiting full amount close to R700 per month since Nov.2021 and in the new year 2021 Jan, I was debited twice. Trying to resolve the issue since the first month, but the head office is claming the club manager is not responding and the club says there is nothing to be done on their side. I'm going to reverse all debit orders at my own cost (R40 each) and then close my bank account. They are not interested to sort out the issuse of their own member. I know Planet Fitness won't respond to this complaint, but I'd like to share my experience.
