I don't mean to be conspiratorial, but I don't see solid evidence that this is not a scam.
You are turning the tables. Suggesting someone is scamming you need evidence first. Not the other way around. 'I can accuse or suggest he is scamming as long as my money is locked', is false and unjust to him.
Personally however I am very open to that this just is a major fuck up on his part.
To me this looks like another major
fuck up holdup by a government. Point the finger to the one locking your money. Not the one that is also a victim.
