FNB INSURANCE SUCKS

We have insurance with fnb, I have an accident on the 1st of July 2022, till 2day the 11th of August 2022 im still getting the run around. Agent dont know what they doing, i dont understand if company has policies in place, why do the agents dont know the correct procedures. Imagine my claim still going on from the 1st of July 2022, the appointed assess took around 27 days to get to my vehicle and asses damage. I have car hire for 30 days and extended it with an agent, i was debited and charged but FNB wont honor the agreement. Now in still with Rental car and apparently i have to pay for it even though FNB has debited my account and say the agent was not supposed to add on 60day car hire and debit my account. I have tried to reason with FNB but seems like every manager i speak to gives me a different story.
