Order paid in ful - no service?!

I called for a quote to repair a broken window late October. After a week I was finally given a quote. I paid the order in full on 5 November and told that installation will take place in approx 10 working days. Its been almost a month and NO feedback received. The staff do not respond to emails. They also do not answer their phones every time ? When asking why no one answers the phone I'm told that there is only 1 person that handles the phone ?? I've emailed and phoned last week and was promised an update. Its a week later and NO one has bothered. Still stuck with a broken window (paid in full)! Never, ever will I use Elwierda Glass again.
