Glasfit Kempton Park unable to fit Glas

Glasfit Kempton Park is unable to organise a ****up in a brewery. I have been waiting for my windscreen to be replaced for the last 3 weeks. They have been advising that the installation will happen tomorrow for the last 3 weeks but to no avail. I think the problem is that there is no tomorrow in the week names so that is why it is not happening. Truly the worst serves ever
