ABSA idirect car insurance

A week ago I wrote a review about my experience with ABSA idirect car insurance company, they rep**** privately saying they will investigate, I attached the screenshots of the agent that was supposed to help me, she told me that she can’t authorise the repairs until I pay the March premium (of which were paid in February by the way) I received a call from the agent on Friday the 28th apologising for her “mistake” and she said she has sent the authorisation to the panel beaters. I’m supposed to return the rental car this Weekend, I asked them to extend the rental since it’s their fault that the parts were only ordered 3 weeks late and I have been calling them for the past 3 weeks to rectify the issue, they have been playing hide and seek. The parts will take 2/3 weeks to be delivered, another 3/4 weeks to fix the car, I might not have a car for more than 6 weeks but they’re refusing to extend the car rental, all I got was an apology, now no one is replying to my emails, they don’t want to pay for a car hire but they get their money every month on time. Their own agent messed up but I have to suffer and pay more money for an uber everyday.
