Claim handled horribly

Horrible service from Miway appointed service provider. Got an instruction to take my car to a miway appointed service provider after submitting a claim, I took the car in on the 17th of April and was told repairs would take 10 -15 working days. It's been 7 weeks now since the car went in for repairs and I still do not have my car back. It's despicable that I should have to wait this long for minor repairs to be done on my car. I have called miway to ask where the hold up is since it is their chosen service provider and I believe that they ought to take responsibility for the horrible service. I've called twice and both ladies I spoke to promised to call me back but did not do so. If I had an option to give no stars as opposed to the one star im giving this review I definitely would.
