I cannot deal with the level of incompetence!

On the 9th of January I was involved in a car accident and my car was referred to Barney's Panel beaters. Not sure why this particular panel beater was selected but they have weighed my patience. It is now going on 2 months that I have not had a car. I was never kept in the loop about any issues that arose, I always had to make the initiative to find out about my car. The main reason I got car insurance was to ensure that in the event that I was ever involved in a car accident it would be a hassle free environment and that I would be doing business with people that would live up to their promises as I make sure that my premiums are always paid. I am extremely disappointed in the service that I have been subjected to by being a client of yours. This particular panel beater in question would not give an estimate on my repairs. I only ever got an estimate after lodging a complaint on Twitter and an employee at this establishment said and I quote \I will have your car ready by Wednesday\" which he didn't live up to because he claimed that they were still missing parts which causes me to believe that the parts were never really ordered in time. Please get efficient service providers"
