Unauthorised debit - end August

My bank account was debited for an amount of R918 this month, after I have sent an email to *** and have tried on numerous occasions to contact the call centre - none of my calls have been answered and Virin Active has not responded to or acknowledged any of my emails. The automated return message highlights that memberships will remain "frozen" until October 2020. I am frustrated that this money was taken and I am unable to dispute/reverse this debit order. Initially, it was so gracious of the company to halt debit orders at the beginning of lockdown, but then to take money at your convenience and my inconvenience is completely unprofessional.
