Extremely disappointed new member!!!!

I just signed up with Discovery on the 31st of Jan. The sales consultant told me that my commencement date was going to be the 1st of Feb 2023 and because my pay date is the 1st of every month, I would only be debited on the 1st of March. I asked him if it would be a one time payment, he said yes. However I just looked at my account and saw that they had double debited me. This is my first time with any medical aid company. My salary is quiet limited but I made a sacrifice and opted for discovery key care plus because I thought it would be affordable. I was debited for a total amount of R2760. I don't even have money to buy anything for the rest of the month and this is totally unacceptable. To be a first timer and have this on your first time of signing up, it utter nonsense. I logged a complaint and was told that I needed to wait for another 2-3 business days to confirm if my request to move my start date from Jan -Feb will be approved. What is that even???....I never asked for my start date to be in Jan, I was told it would start in Feb. As it should, because I signed up on the 31st of Jan and don't understand why the sales agent would do such an awful thing. I need my money back as soon as possible!!

I'm now considering to cancel my medical aid. I really don't feel that I was treated fairly.
