As many people have told you, you'll need to contact HTC. You can blab on and on here but that won't solve anything. You've gotten the e-mail twice and the phone number once. If you don't want to make the call, send an e-mail and someone will respond.
Also, Krusty clearly told you how to report someone.
I can't stress this enough, nothing will get solved on these forums, so it's best not to complain on here and risk getting yourself banned here too.
