Безопасен ли skybox.net?

Terrible service. The customers' service SEEMS very helpfull as long as no transactions are made yet. Once you do, they find one reason after the other to take your money: insufficient information will probably lead you to having to create a second account (and even others), then they make transactions without your permission and claim it's you (being new) who made the mistake (and you can't prove the contrary of course), then - even though the calculator tells you "Total Custums: 0$", you end up paying almost 30$ which they justify as: "Actually there is no customs to pay, only the VAT 17.5% of the cost of the goods, plus the processing fee, plus the brokerage fee". I made an order on amazon for a total cost of 43,91€ (a small package of 0,75kg) and I ended up paying 79,62 to skybox to get it delivered (USA => Barbados)
