Where can you go to replace windscreens because the service is generally shocking

On Monday 11th December I visited PG Glass in Allen’s Nek to query replacement of my windscreen on my Audi A4. The Staff member at PG half heartly with very poor communication only said they do not claim through Budget. No inspection was done or attempt to provide service. On Wednesday 13th December at 12:27 I contacted budget to replace my windscreen. When I submitted the claim I provided all the relevant vehicle details. The Budget insurance consultant assured me I would be contacted by Glasfit immediately. The first communication I received from Glasfit was an SMS indicating my claim had been received and on the 14th December 2023 I received an SMS providing a reference number and that my claim was processed. On Monday 18th December 2023 I received a call from the call centre and was told I would be contacted by the branch. I had not received any further communication from Glasfit and I contacted the Offices in Roodepoort at midday. The staff member receiving my call was very unprofessional and asked all the questions I had provided to Budget and the call centre. On Tuesday 19th December I received a call from the Glasfit branch again requesting my car details again. I was informed my windscreen would be replaced on Wednesday 20th December between 9 and 10. When the technicians arrived after 10 they told me it was the wrong windscreen and they would have to come back. I then spoke to the branch indicating the mistake was unacceptable and they promised to return that afternoon. I was contacted by the branch to fit my windscreen on Wednesday afternoon but when they arrived at 4 they could not fit my windscreen because it was the wrong windscreen again. I spoke to the branch manager and indicated my dissatisfaction with the process to date. The branch manager refused to take responsibility for the break down in service. The Glasfit technicians arrived on Thursday 21st December 2023 at 15:53 to fit my windscreen but indicated they do not have all the correct parts and would need to return the next day to fit my rearview mirror. This will be the 4th visit to my place of residence and countless hours wasted waiting for Glasfit. I feel like the partnership between insurance companies and third party providers is limiting the options of the consumer to use a reliable and efficient service
