Terrible service

Unacceptable service. Took 2 weeks to Inform me my windscreen had arrived as was a special order, this being 20/03/2020 Also informed during the same phone call that PG glass will schedule an appointment for fitment. I received a phone call on 25/03/2020 to ask of I was available for fitment, to which I rep**** no, and requested my appointment be scheduled for the next day 26/03/2020, the technician responded in the affirmative. Later on, I notice 3 miscalls in the morning, to which I tried calling back multiple times but the call would not go through. Never received further calls during the day. Today I call to enquire as to the delay of fitment scheduled, spoke to Devlan, who says they are closed today, nobody is at work due to covid 19, wondered if I was aware of this, and they had called all their clients to inform them of this. After much arguing, they could not assist me. I am deeply upset as I am an essential worker required to be at work during this period, and now driving around with a cracked windscreen, being blamed for my not being available for fitment. Yet no one had called to schedule and appointment, Dee had only called on the 25th, 3 working days later of receiving my windscreen, to say they would like to fit it on that day, aware that they would ot be working on the 26th.
