Poor service and customer treatment at Discovery Insure

I am still waiting since June 2020 for my car claim, claim no ***, to be paid in full, been a struggle to get them to process the claim in the first place and then they neglected to pay the credit short fall which I was covered for and which they agreed upon. I have an email stating it was paid from Claims Consultant Ushen, that was also last year, since then I can't get hold of them and no answer. I am still being billed for my written off car. And the credit short fall was not paid.
