Pathetic Service!

Pathetic service that I got from Miway. Beginning of February I got into an accident and I have put in my claim. Everything got authorized and had to take my car in to the panelbeaters. Then a day before, something just told me that I must just confirm with the panelbeaters what time I can bring my car in. The lady then said that the claim was cancelled. I immediately contacted Miway and they said to me that is I cancelled it via the web. BUT I DIDN'T!!!! never did I cancel my claim as I wanted to get my car fixed!!! So they resend the authorization letter to the panelbeaters. My bumper had to be fixed and due to the impact from behind, my windscreen cracked as well. My car is ready to be fetched and they have informed me that my windscreen is not replaced! That it is unrelated to the accident! and that it must be a separated claim, so again, I have to pay another excess to get it replaced! They said that the crack was already there before the accident and that I'm lying. This is utterly pathetic!!! I am cancelling my insurance soon and will be moving to another.
