MiWay is absolutely useless

I have insurance with Miway that includes tire and windscreen damage. Got a flat tire after hitting a pothole, and Miway have been absolutely useless!! I might as well just replace tires with my own money if it takes Miway more thank a week to replace! I need my car for work, it's been a week and I still don't even have a plan in place from MiWay on how this will be resolved. The run flat tire is now completely deflated, so what, must they now tow my car when they finally process the claim, for a flat? Will highly discourage others from getting this kind of insurance from MiWay, it's less hassle to replace something so simple as a tire yourself, atleast you won't lose your car for a whole week (and who knows how much more time at this point). Useless.
