Miway and the panel beaters are rogues stay away

So Miway have decided to write my car off because the panel beaters have over quoted them. They won’t even give me an option of checking another panel beater and they say if I decide to do that then they won’t pay. Now if my car is a write off, then I’ll have no car because there’s no way I’m starting all over again when there’s literally two years before I finish paying my car off. I’ll probably buy a car cash in December and will never use Miway ever again. Since pineapple is getting good reviews I’ll hop to pineapple and also encourage my husband to never again use Miway
