Virgin Active non cancellation

My husband cancelled his membership with discovery vitality and virgin active during the Covid period. No issues with discovery vitality but virgin active continued debiting his account with a full membership fee of R600 with out his permission. he spoke to an agent on numerous occasions to resolve this. Eventually the debits stopped. He then re joined a month ago with vitality as well as virgin only to find out a week after he joined again that virgin has handed him over to debt collectors for no payment. We have been trying for 2 weeks to speak to someone to try resolve it again to no avail. Calls just get cut off at the call Center. Tried talking to someone on there Facebook messenger platform with no success and then numerous emails to the escalation department and still no luck. Just zero help and the most shocking replies from the various agents I have interacted with. Cannot believe that in times where business needs members they turn a deaf ear to my requests to resolve a very simple matter.
