No response to enquiries,owes rental car deposit

After I was rear-ended by someone, I got a rental car as stipulated on my policy. I phoned at least once weekly to confirm that the car rental is extended. Each time Santam said that they are extending it and that they and/or Europcar would contact me regarding the return date of the car - that I should not worry.<br> <br> They never contacted me once. I attended a conference out of town, and as soon as I got back I phoned again, this time they said I should have returned the car two days earlier. I was not happy with the fact that no one contacted me, but returned the car immediately. <br> <br> When I phoned Europcar two weeks later about my deposit - they said they are keeping it for the extra days I had the car. This has been dragging on for more than 40 days. Santam never gets back to me regarding this money, and I will NOT accept liability for those extra days.<br> <br> For the price I am paying monthly the service is terrible. I am so unhappy and have no idea where to turn to for help anymore.
