There are many ways to deal with bad behavior.
One is to engage in some verbal jousting and -- without being a jerk yourself -- give some back. This can be great fun depending on your personality type and debating skills.
This route definitely isn't for everyone, though, as for a lot of people it will just devolve into unpleasantness for them.
A second is to ignore it and work on it not bothering you. The world has plenty of jerks. In fact, the world has plenty of people who, if they had the chance, would like to kill you. Not getting upset about what they have to say or how they feel about you is a good skill for life in general.
A third is to report it to HTC. Film it and e-mail the film to support at hitechcreations.com
To do that, open up your e-mail program, and there should be a button or menu item somewhere for selecting attachments.
Tracerfi, going the e-mail route is good -- also working on the aspect of ignoring and not letting it bother you will help.
Best of luck, and you have our support!
