POOR SERVICE AND RENTAL CAR

I m insured with Hollard since the purchase of my car in 2012.<br> Recently been an accident and put a claim through to hollard. they have delayed with processing the claim and repairing my car till to date. my car hire has now expired and they will not extend the rental. <br> they are constantly pointing fingers at their service providers and not accounting for the delay. I am frustrated as they want me to return the rental car while my car is still in penal beating. They should be liable for all the delays and not push the blame. its their selected accesses and their selected penal beaters. so they should account for their actions. Please assist me in get my car back or a further extension to the rental. <br> I have been in contact with them and they are now telling me to see fit...
