Delayed parts and an Inconvenienced customer

Had an accident on the 11/06 and still waiting for parts to be delivered for the panelbeater to be able to start working on my car. it is going for the 2 month and i do not have a car. As the delay is on their side i would expect them to make arrangements for me to get some form of transportation instead I keep on being told that the policy does not allow because of warranty/ service plan. Why arent you writing up a policy for contingency plan for when you inconvenience a customer because of your incompetence. they are all a bunch of *****. This Keeran character that I spoke to 3 weeks ago promised to call me with updates and till today I never heard from me until I call him this morning only to be told the same thing i was told 3 weeks ago. Now he promises to call me again today with feedback. What makes him think that I believe that. These people do not care about their customers and make up policies just to excuse themselves from taking responsibility for their failures.
