Has anyone claimed for a replacement screen through Adrian Flux?

I need to get one sorted on my derv, and I'm due to be going to Edinburgh (600 mile round trip) on Thursday, so need it sorting asap.

Tried calling their customers services, but they work 9-5.30 (Great for anyone who works in them hours).

I need to know how quick they can have it done, and also will they allow me to use a friend who can do them?
