The website actually has mixed reviews coming from the users. There are those who seem to be satisfied with the service and there are those who are not satisfied with the service. It is almost an equal ranking in terms of service satisfaction, or lack of it. As always, it is better to believe the worst in these companies because the background is quite shady if you delve deeper into it.

Would it be possible for you to post a copy of the conversations you had with them leading up to the lie about the refund? It would help add credibility to your claim about their having scammed you in the event that their company representative comes across your post and decides to belie your claims.
