When is a Chevy not a Chevy

Any of you Chevy chassis owners ourt there been silly enough to Go to Chevy uk with a problem or wanting help with Chevy type things. I was, I lost my egn. key so rang my local Chevy agent, they said come with log book and we will get you one..
When I got there I was sent to the parts manager who said
NO you want Chevy not Chevy. AAAAAAhh I said what do you mean. Well he said you own a Chevy.... We sell Dawae cars that are branded Chevy, we have no connection at all with Chevy.
Did any one else know this ? maybe some one how has a nice new Chevy that was made in the jungle and isn't........
