I had a few phones call today with inbox which gave us a 100% verified identity, ID & proof of residency, which of course we will not disclose with anyone.
We have unfrozen his 262.71142052 MSC and put them in a new account of his choice.
There is enought reasonnable doubt that inbox was indeed good willed to trust that all this was a huge misunderstanding.
We thank him for his good willingness in the resolution of this issue and hope he will not have hard feelings.
