I'm finding the same with Audi dealerships. Stafford Audi didn't get back to me after I went in and talked some figures over used cars. Twice I've sent enquiries to Stockport Audi over a used car online and they haven't contacted me at all.
I got into the early stages of a new car order with Stoke Audi until they started ignoring me.
Coventry Audi have been good but I've got a better deal now through Orangewheels (others were carwow) so not sure yet which dealership I'll be dealing with...
I know they're very busy but all I want to do is buy a car..
