They are bad thieves. They are incompetent an try to steal your money. Use PayPal so you stay in control. They said they could unlock my Z10 and to pay. I paid then the email came saying they can't unlock it after all and I would get a refund in 3-5 days. I was upset that it takes 3 -5 days to click a PayPal refund button. I waited 1 week... no refund. I emailed Where's my refund! I got a reply that it could be 10 more days and if I don't see it to email again! Are you serious! I emailed a threat to contact PayPal if I didn't get a refund within 24 hours! They had to ask for my email to send the refund? This company should be shut down and investigated by the IRS! They gave my refund after the threat.
