Unfairly Treated

Last year I was requested to submit my income verification documents on time. After i did so they went ahead and place me on the low income band and not the student bracket, meanwhile I had submitted everything they required me to submit. That means in January the premium deducted was wayy more than what they should have deducted, it was just above R1500 instead of around R900. Later in Jan they fixed my income verification after i submitted the very same documents they requested and received last year November. Now i am querying about the high debit order they deducted earlier in January and they telling me that they cannot credit/refund me my money, which i do not understand because it is not my fault that i was placed on the wrong income band, I initially submitted all the documents they wanted from me. I am highly highly disappointed in this medical aid, and the worse thing is that , I experienced the same issues in 2023/2024. Unfairly treated because of someone’s mistake in the company and also being ****** money, this is really not fair especially because i am still a student.
