Poor service from PG Glass Centurion & PG Glass

So, PG Glass received my claim for a windscreen. PG Glass Centurion called me on 20 March 2019 to tell me that the supplier can only supply them with the item between 14 - 21 days. After asking to call other suppliers they came back with the same answer. I was then promised that I will be called within 16 days for an update. I called on 09 April 2019 which is 13 working days later (20 Days in total). Just to be told I am scheduled for 15 April 2019. The person that supp**** me with the date could not tell me why I was not called and informed. This is the second time in six months that I received poor service from PG Glass and I will take this to the insurance company as well.
