The true identity of "Mr. Lee" (he is the owner of MecaCex) has now been uncovered — and as suspected,
his name is not Lee, and he is not Korean.
He is originally from Vietnam, specifically from Quảng Nam Province.
His personal internet provider is Viettel Group.
His private email address is:
ozinexexchange@gmail.com (a old exchange?)
This means that if someone has been cheated, they must file a report with the authorities in Vietnam.
