Disappointed with CAMAF in the handling of a claim due to their errors

I had good experiences last year with CAMAF however this year I had a procedure on the 29th of April, it has taken them over 3 weeks to get the surgeon paid, they firstly short-paid the surgeon and it did not match the quote provided by CAMAF when the approval for the procedure came through before the procedure; secondly I had to follow up and the person at the Call Centre told me wrong information, I had to resubmit the invoice and they are now still reprocessing, it's been over 3 weeks and I still need to submit the shortfall to the gap cover, which will take another 2 weeks. I have been very unhappy with how this has been handled and the time it has taken.
