So, I went in to a different store last night and played dumb consumer.
I said, "I bought this new Nokia last week and when I was on Nokia's website today I saw I was supposed to get a free charging thing for it. How come I didn't get one?"
"Lets take a look at your account."
The salesman was also a 900 user, so maybe he liked that I had bought a 920...
I saw him and a co-worker discussing what they could do, while I "shopped" the store.
I overheard the co-worker say it was only for people that ordered online.
..More muted talking..
Came up to me to confirm shipping address, and now my free charging plate is on it's way to my door step..
-For those of you that didn't get one because you paid no commitment pricing.. give it a go at a different corporate store.
