Poor service

I had a car accident december last year.I was si impressed at the way my claim was handled and I thought it was fast until my car was sent for repairs.Car went to dealership on 10Jan,waited for parts for weeks,I enquired after a while dealership said KingPrice just approved additional parts,King price said dealership ordered wrong parts.Parts arrived at last ,Est completion date went to 06/02.Come 06/02 it was changed to 22/02,come 22/02 the car is just going to be assembled and tested will be ready in 3 days.Monday dealership calls King Price just approved additional parts costs now...again...they will arrive 1st March.I feel very dissapointed now,lost confidence in both King Price and Technicolor...I thought having Neil Van Loggerenberg, as my King Price client experience warrior on the case will make the process bearable,I actually thought he will be checking up on the progress and updating me and facilitating the whole process.Even audatex-if I remember the name correctly no updates.Now Im just waiting for that time when they will be finished...dont know when.?
