Beyond mediocre service

I took up membership with Premier Private Resort. Worst decision of my life.. Membership number ***. They kept on messing up my account for an amount of R170.00 which I didn't even owe. As a result I was listed at the credit bureau. I then took a decision to cancel my membership and spoke to Prabashni who was very helpful. I was told that in order to cancel I needed to pay R13 285.19 which I paid in full at then end of 2022 and was told cancellation period take place between Jan to July so only in 2023 will the cancellation take effect. I had no issued with that. January 2023 I sent an emai; reminding them of the cancellation. I was told that they have sent to the relevant department. Fast-forward to January 2024 I get send statement stating that I owe R11 306.00 and the R170.00 that led me to cancel with them is still showing... They even have the audacity to hand over my account. I have an implacable credit history and their mess up has really frustrated me. When I call to ask why my membership is still on I am not given an answer. Instead I was told about the benefits that I still do have on the membership. NOTHING WILL MAKE ME REINTATE MY MEMBERSHIP WITH PREMIER PRIVATE RESORT. They are the worst people I have ever had to deal with.
