Ist apez.biz sicher?

I don't know what category to put this in so I chose phishing or other scams because of the nature of how the site operates now. The site allows you to transfer linden currency to their website and then sell it in exchange for usd. When you sell them your Second Life currency (which can be sold on Linden Labs website for real life currency) you can have them pay you for it by sending the USD to paypal. They say "instant transactions for qualifying members." I've attempted to sell my lindens in exchange for usd and they claim that the exchange is no longer pending. In other words they claim on their site its been sent to pay pal when it has not. I have not received any contact back from the site owner in a week, nor my money. This has apparently happened to several others looking at the apez.biz forum.

I'm a member of apez.biz user base, I have had issues with them not allowing me to withdraw 'my' funds. Further investigation results in many other users facing the same issue. This is an notable issue due to the sever lack of customer support. Highly unprofessional customer support is the basis of this comment.
