Freewallet is not a legitimate company anyone should do business with. They are a front for organized crime. Their registered company address in Hong Kong is not legitimate. A Google search will show thousands of users posting on Reddit, Facebook, Twitter with complains about their accounts being frozen and their funds stolen.
They claim to have 24/7 customer support. Service tickets go unanswered for weeks, their chat tool is a bot that does nothing.
They are THEIVES AND CROOKS. I have reported them to Apple store and Android app store hoping to get them removed. If you send coins there, you will never see them or your money again.
