Virgin Active Bryan Park Withholding Money They Must Refund

I joined Virgin Active in the Bryan Park shopping centre in December of 2022 on the basis that the monthly membership fee would mostly be covered by Discovery Vitality. Discovery then cancelled my Vitality and the Virgin Active membership could not be activated. I had unfortunately paid an activation fee to the club prior to Discovery having cancelled my Vitality. Staff at the club have confirmed that the membership was never activated due to the aforesaid reason and that I would be refunded the activation fee. I have, since the 06th of Feb 2023, been attempting to have the Club refund the activation fee. In the latter regard, I have been in contact with a certain Diovano and Zanele employed by the Club on at least 4 occasions. Zanele had twice advised me over the telephone that the refund would ensue, but it's been 6 weeks since the Club's first confirmations were communicated and to date, nothing has been refunded to my account.
