Bad service

I am kindly writing to complain about the poor service that I have been receiving from PG glass Allen's Nek. My claim was paid on the 26 of September and till today they failed to replace my windscreen. I really am not happy with how they assist their customers and not give us the best value for our money. I have been to this branch 2 times , forcing myself to drive with the ankle that is healing from the recent operation I did. I have wasted my time and my petrol for always being told that the glass is not available at the branch and they are not sure who was dealing with the quotation.I have even requested mobile service but still I am not being attended to. No one is assist unless I take my time and call to check with them regarding the claim or time appointment for the glass to be replaced. Today I called the PG Glass call center and apparently there were no bookings that were done for me for today but I received a text to confirm my address for booking done
