Shocking service

I have been trying to replace my windshield with PG Glass since 1 December (12 days ago) with no success. I shattered my windshield on 1 dec. On calling I was told the sandton branch would have the appropriate glass for me by that afternoon. They then rescheduled for 10 on Monday 4 Dec. I went in and waited until 12 before they told me they could no longer get the glass and I should use the mobile unit instead. They then erroneously booked me in for repairs in Cape Town instead of Johannesburg. I was told after rectifying this that I needed to pay in advance to confirm the booking for repair to be done on Monday 11 Dec. I had to call twice a day for 4 days before I could get an invoice, eventually paid in full and no one arrived on the scheduled day and no one bothered to phone to cancel. After 3 more calls I finally got through to a manager who promised a temporary fix as the glass will now take a further 3-5 days as apparently the glass ordered for me was given to someone else. I have now been using uber to get to and from work for 12 days at massive expense with absolutely no updates or feedback from PG Glass yet they have taken my money. I am still yet to hear back from the manager who promised to sort it out and get back to me today
