PG Midrand surely cannot take accountability

Hi Peter, I have ordered a new windscreen from PG glass Midrand via Audi for an original windscreen and after much poor service I finally received the call to state that I need to drive into PG as they DO NOT offer a mobile service unlike many of their competitors. I found this very strange but the glass was already ordered so I agreed and drove into the branch 3days later being a Friday afternoon at 16:30 of which the manager Andrew agreed to install my glass because they were closing at 5. After arriving here Andrew and Olver stated that the guy who installs windscreens is leaving so they cannot assist me. Anyone of them could of called me to state we cannot assist or we closing instead you call me at 16:10 to say that I CAN come through? Firstly I could of done this R6000 claim through anyone but I chose to do it with PG and this is basically the service you got to get back. I just want to say that PG glass Midrand surely DOES NOT go the extra mile for clients or myself specific and it's surely the last place I will recommend you to go to if you looking for more than just a basic service.
