Very poor service and no call back from KP

When we submitted the claim KP awarded the deal to Auto Magic, who was swift in assessing the vehicle. It took 2 weeks to approve the claim. The vehicle was delivered to Auto Magic on 2 Mar, who promised the vehicle would be repaired on 16 Mar, on the day I contacted Auto Magic only to be told there as a delay and the vehicle would be ready on the 18th. Today i am told they are still waiting for a part and can not tell me when the car will be done. There was no follow up from KP and five phone calls later today and numerious promises to still no call back from KP. Where is the royal service, you forced me onto a poor service provider, not for the first time i must add and now you simply ignore the problem.
