Service not delivered.

My car window got smashed on the 27th December in the early morning. I called my insurance and they referred me to Glasfit Middelburg because it was the nearest for me. They got hold of me and I was told to bring the car the following day. I went and dropped it off. After an hour I was called to collect itbecause the glass didn't fit. When I get there, the lady tells me I've got bad luck when it was their fault. When I tell her it was their fault she tells me they'll be able to fix it second week of January if their other supplier doesn't deliver today. I'm still waiting no one has called ever since yesterday. When I tell her I'm supposed to use the car for our family vacation she said its up to me what happens next. Do you say such to a customer when you're the one that inconvenience them? She's very rude. I want my window fixed by end of the day.
