Still no service from PG Auto Glass

On the 21st of January 2016 I registered a claim with my insurance company for a replacement windscreen for my Hyundai i10. (BC39RC GP) The claim was processed with no issues, I was then told to phone my nearest PG Auto glass branch which is Centurion to make sure they have stock and are ready for me. It took me 4 days to get them on the line, they either don't answer their phones, place you on hold or put the phone down. I have even tried your support agent \Andrew\" on your website I furnished him with my details and I was told they would call me back. I then contracted their national number and spoke with a lady who yet again took my details, after which she said she will call me back in 15 minutes. I received a call back and was informed that she contacted the Centurion branch and that they will contact me back in regards to a replacement windscreen. This was 3 weeks ago. After expressing my grievances on Hellopeter and Facebook I was contacted by a regional manager and promised that I will be contacted within 2 working days. This is 2 weeks ago... http://hellopeter.com/pg-glass/complaints/terrible-service-from-pg-auto-glass-***"
