Re-Newit Greenstone

Mutual Federal motor insurance - appointed service provider Renewit Greenstone Edenvale to repair damage to my car, 2months ago. Informed that my car was now available for collection on the 25th January 2018. On arrival, my car was far from completion and the staff had a complete disregard for my dissatisfaction: They wanted to hand over my car that was not road worthy or fixed to the same level prior to my accident. The windscreen was cracked, and I was informed that this was not part of the claim. But surely the assessor from mutual and federal and Renewit have not done their job correctly. The car was a disgrace and the staff member even lost his temper and threw the paperwork on the bonnet of the car and simply shouted that it is not his problem and they will just take the car to the yard and leave it there. Is this the type of providers that Mutual and Federal appoint? A panel beater who produces this type of workmanship and deals with customers in such a manner. Does Mutual and Federal not have staff that inspect their service providers, to ensure that a that a level of service is maintained to a standard .
