I joined the Microsoft App Hub after receiving the Lumia 800 to check out the development cycle. I followed the instructions and used the same email address on the apphub as I did on launchpad as well. Now Its been almost 3 months and I have yet to receive my $100 refund.
I tried contacting microsoft at firstname.lastname@example.org but never got any reply. I have no idea who to contact on Nokia's end either.
Would love some guidance!
