GTP said that I'm a Resident Alien so I want a refund of my GTP purchase price.

As indicated on the Individual Use Sales page, you are asked to enter information about your tax status so that we may determine whether GTP is the right product for you. Based on the information you entered, you were determined to be a nonresident alien. It appears that you entered different information from what you provided to us at the time of purchase so we will not provide a refund.
