Pathetic Service from Auto & General...only allow their Service Provider to Fit **** and Generic windscreens

I am absolutely distraught from the service received from Auto & General Insurance. I called them on the 6th May 2026 to assist me to log a windscreen claim for my cracked glass. I spoke to a consultant and was advised to log in the claim on the app. I also brought to the attention that my vehicle is under warranty and I require that an original windscreen needs to be fitted. I was advised that will not be a problem and the original will be fitted by Glasfit. I captured the claim on the app with all the required info, photos and also specified an original windscreen be fitted as the vehicle manufacturer requirement due to the sensors and cameras to be functioning to full spec and eliminating malfunctions to my vehicle. I got a message a day later stating the claim was approved and Glasfit will call me. Glasfit called me on the 8th May 2026 and advised they can fit the windscreen. I asked Glasfit are they fitting the original windscreen as I advised Auto & General with reasons. Glasfit advised they were going to fit a Generic Windscreen, I advised them I already spoke to Auto & General of ensuring the original is fitted. Glasfit advised, they will check with A&G. I got a message on Monday 12 May 2026 stating my claim is approved and its assigned to a particular consultant. I received no call or feedback. I responded on the app to the consultant stating, I received no feedback and reiterated the original windscreen be fitted by Glasfit and stated that I received no call from them nor Glasfit. I still didn't receive no response. Only today 14th May 2026, Glasfit calls me and advises me that Auto and General refuses to allow them to fit an original windscreen and I must contact them as my claim has been rejected. I then call A&G, spoke to a claims consultant of the claim, who gives me excuses and tells me their policy is that I must get a letter from my manufacturer to state I need an original windscreen becos my vehicle is in Warranty and due to the sensors and cameras linked to the windscreen, I require an original windscreen and not a cheap **** or generic. All he could keep repeating himself about 10 times to say his sorry....I must go through all of this, never claimed in more than 2 decades, I have 2 vehicles, household and personal insurance with Auto & General and receive this type of service from these clowns. Do I deserve this from being a loyal customer? I must do all their admin work? I must follow up? Receive no communication and feedback, their silly app is useless. What type of service is this from a company that supposed to be reputable? If this is the type of service i'm getting for a simple windscreen claim, what service will I receive if i'm involved in an accident?????? I have no faith and any confidence of keeping my insurance with Auto & General going forward with this ridiculous service that i'm receiving. If I get stopped by the police and fined in the next few days, I will take Auto & General to Claims Court and compensate me for all of these inconveniences
