Poor service

I've got an approved claim with Miway but it seems like getting a courtesy vehicle is mission impossible. At first I was told I must book in my vehicle between Monday - Wednesday only and I must confirm that the panel beater has parts before they will secure a courtesy vehicle. I ensured I booked my vehicle in on Monday as Miway required and I also called the panel beater to confirm availability of parts. I then called Miway to confirm my booking and parts. Then they then told me that its them who must confirm that the dealer has parts available. I told them to call the dealer to confirm parts. Its been 2 days since I notified them of my booking and requested them to confirm parts., I've been following up with Miway past 2 days with the same request. I still don't have confirmation of a courtesy vehicle and they still have not called the dealer to confirm parts as per their own process.

Right now it seem to me that they are trying to save money and not book a courtesy vehicle which will leave me stranded. I cant understand why they cant just call and confirm or give me guidance of when they would like to arrange a courtesy vehicle so I can arrange my booking accordingly? This whole process is complicated and its also time wasting my as everyday I must call Miway to check if they have done their job.
