Bad service from PG Glass Call Centre

On Tuesday I called the PG Glass Call Centre to place an order for a cracked car window. The lady at the call centre was very unclear and I had to ask her several times to repeat what she had said. She was very vague about everything and I struggled to get information from her. Finally I got her to understand what I needed. She said she would place the order and the window would be delivered to the Garstfontein branch on Wednesday around 1pm. I arrived there this morning (Thursday), after driving around for 20 minutes, unable to see any PG sign from Garstfontein road. When I asked at the office, they had no such window and had no idea what I was talking about. They were not very helpful and just said that there are always problems when one calls the PG Glass Call Centre with a cash payment order.
