If you cannot find the parts FIAT say they have them all

I was quiet for a while, now I'm I no longer going to hold back. My vehicle has been standing there for five weeks come tomorrow. Living across the road from a FIAT dealership I took a copy of the assessed quote to them. They confirmed that all parts are available locally and that their time to repair would have been, worst case scenario, 2 and a half weeks. Now you tell me. Monday becomes Friday which becomes Monday - good grief man!
