Bad service from FNB Insurance

FNB Insurance is the worst insurer I have come across. I was involved in an accident on the 15th of December 2023. I fully understand that Panelbeaters and assessors were not available at that time. The consultant went on leave and approval for repairs were not carried out because she was not available. FNB is the one which delayed in approving the process but I am the one who's going to suffer for the next donkey weeks as I have to return the car to Avis. I know that I only had to use the car for 30 days but I still maintain that the insurer failed me.
