Horrible way to treat a customer. What OP experienced was a very strict fraud prevention system. I'm not trying to excuse HTC in any way, they should have a way for a manager to override. Nevertheless, I thought I'd share my experience with a different company with similar anti-fraud policies. Should anyone find themselves in a similar situation, call your bank and ask about adding an additional address to your account. This way the address verification check with the processing gateway will succeed when your shipping address is submitted.
