Appalling Service, such a disappointment.

I submitted a claim last month, was given a courtesy car for 30 days, I had to return the courtesy car. Their repairers are taking too long to repair my car. When I called in today, my insurance informed me that the repairer needed to provide me with a courtesy car (bare in mind, I have no contract/business with the repairer, I don't even know them). After speaking to the repairer, the consultant told me that the repairer had no courtesy cars available at the moment and that I would be put on a waiting list... like that will make my situation any better? this is ridiculous service, had I been given a cash payout, I'm quite sure my car would have been repaired by now. In all this, no one is bothered, but myself because I'm the one being inconvenienced!
