Poor Service Delivery

I sent an email with a request to cancel my membership on the 6th of August 2023 of which it was a few hours after accepting the agreement on the same day. I then made numerous follow-up to get feedback on my cancellation and I keep getting the same response; that my cancellation has been processed and I will be receiving my refund within 14 days. Two months later, I still haven't received my refund and they’re still attempting to debit my account for their membership fee. When following up the cancellation I’m told the documents are with the sales agent for processing, or they are sitting with accounts and have been processed. My last follow-up I am told my banking details are incorrect. No one attempted to let me know, I had to follow-up to get the information. I don't know if it's a matter of incompetency or poor service delivery. I am very unhappy about this treatment. It takes ekko two minutes to debit my account when taking up the membership but months to cancel the membership and get my refund.
