Bad service ever

I changed my address via the app and they debitted a prorata of which by that time I ddnt have in my account, I also changed the primary driver which made my premium to be less, I was then advised that I do have credit due to me, after that I requested my access fee to be changed to R5000, I was advised that the premium will be R1700 I agreed, on the 20th of July R1500 was debited I assume it was becoz of credit due to me. I received the policy document with the old acess fee of R27500 with the premium of R784, I asked what's going on and I was advised that the was a time my policy was canceled how so🙄. Nobody seems to have answers I was advised that someone will call me back till today🙄.,i requested my policy to be canceled however when I login on the app I can see is still active, what do I do here?.. I'm not happy with the service I got honestly
