Pathetic customer service in the claims department

I have been a client of Miway since last year. Yesterday (23/04/2015)I get to my car.The hatchback window is broken, glass everywhere & my GPS is ******.I get a case number. I call miway put in my claim, for the window.The claim is logged and I receive an SMS frm glassfit centre closest to me with a reference number. I am informed they will call me. I wait half an hour, nothing happens, I call twice before they have somebody that can help me(remember this is a client following up) I then have to go through the entire process again to explain exactly what is needed. It is then communicated that they can only replace the window next week Tuesday. This means the car is with a broken window for 5 days! IT's a security risk. I called miway again to assist as this is unacceptable. Nobody can help me and they say that Glassfit is their only supplier, no further sourcing ideas nothing!I suggest to going another supplier that can help me within 24 hours. Then Miway can reimburse me the amount. That's agreed upon after about half an hour of explaining what I mean. But then I still had to go through the entire process on my own without help from my miway.This is no way to treat client.
