Unhappy with lack of communication from PG Glass

I logged a claim PG Glass - Centurion about 2 weeks ago and was advised that it would take a week to receive delivery of a kia sonet windscreen. I have not received any calls from PG glass to inform me of the status of delivery and when my windscreen will be replaced. Every time I call, I can never get through to them. ***. I need my windscreen to be replaced today.
