So if my screen should need replacing, what are my options bar letting the insurance send out an Autoglass monkey? Is it within my right to insist that Ford replace it?
That may well depend on your insurance company, when I had National Windscreens repair mine my insurance company (Flux) recommended me a couple of options but didn't say I had to take them.
Sounds like a nightmare paradigm, I hope you get it sorted soon.
