Frustrated Client

I submitted a claim for damage to my windscreen and PG Glass was appointed. They made contact relatively fast but advised that they would only have the glass at the end of the following week. I called the call center - very unhelpful and rude staff - to advise that I'd procced with the replacement with a supplier that has the glass available and submit and invoice. The guy told me to go "sort it out" and let them know once I've done so. I had the windscreen replaced last week on 26/10/2022 and i have sent the replacement invoice which i have sent to *** and i have not heard any feedback yet. Not that I'm surprised because i always have to call in and stay on the line for a long time only to find someone who must always tell you to hold while they put you through to the windscreen department and that's it! I have never been able to speak to anyone helpful and it is frustrating that it is so painful to be treated with some decency. All i want is for you guys to reimburse me and we part ways. It's sad that i have to resort to this just to get your attention...that's if you'll even respond to this!
