This's totally scam

First they told me they will unlock my icloud for $28 then after two days they send me email to make the final payment that's meaning they check my imei and they ready to unlock my iPhone so i pay $42 then they send me email saying my iPhone is in blacklist stolen/lost and i have to wait for premium service and pay them £49.99 but i have approve that is a lie and i send them the tax bill for my iPhone and screenshot from others website that saying my imei is clean

But they refuse to refund me money to my credit card that i pay with it.

And today they send me mail saying that the premium service is available but i have to pay £49.99 and wait for 30 days to finished the process

I don't recommend this website. It's a Scaaaaaam.
