PG Glass service is atrocious.

I registered a claim for my windscreen 2 week ago with my broker and the claim was allocated to PG Glass. I got a confirmation message on 30 November 2023 that the claim has been allocated to them. They claim that they called me on 30 November 2023 however I did not get a missed call from them. I called them on Friday 1 December and could not get a hold of them. I called again on Monday 4 December 2023 and they said that the claim has been allocated to Midrand. They called me on 5 December 2023 and they said I must go to the branch. I told them that I asked for them to come to my house. They sent the claim to their mobile branch which is absolutely useless. They called me again on 7 December to ask again if i can come to the branch. I told them yet again that I was informed that it would go to the mobile service. They finally booked to come to my house on 12 December 2023. I called them yesterday to confirm the time. They said 1 o clock. This morning at 11:10 I called again to confirm the time and they said that the claim is not authorised. I told them thats not possible. Then they sent a message saying that the claim is authorised. They said that the driver would be there at 11:30. I told them that that is not what was agreed and im not home. I called the driver and told him Im not home as they had said the appointment is 1 o clock. I told the driver, Sidwell, that I would rush home and be there by 12:30. He agreed. I had to move my meetings to accomodate this change of time. The driver rocked up at my house at 13:14, did not even apologise. How a windscreen claim can take 2 weeks is unbelievable.
