Horrible service and no feedback

I went in to repair a chip in my windscreen, with the T&Cs that if the chip continues to crack, I would get a refund, but would then have to go through my insurance to fix it. Fair enough. Once the chip was filled I told the repair tech and the Administrator that I can see a small crack next to the fill. I was told to "feel" the small crack and if I couldnt, then it wont crack. I was sceptical and told them I'd contact them WHEN it cracks. The next day the crack had increased by a few centimeters, followed by a lot more the following day. I have tried to get hold of the company via email and telephone constantly (I am not close to PG Glass Centurion to just drive in), and even wrote PG Glass an official email hoping they would help. Their telephone system is surely broken and no one replies to emails, including PG Glass official. I had a PG Glass admin person call to find out how happy I was with their service. Once I told her about the situation, I was told she would get to the bottom of it all. Two weeks later and I am still waiting. (On top of this, the electronic invoice I would get "the same day of the fix" I still havent received, in spite of my constant nagging for it as well. This is horrible service. There are several other companies you can and should go to instead of PG Glass.
