I am sorry for your headache. I unfortunately cannot offer your much advice as it appears, given wire transfer that your money is definitely gone. Whether you’re able to secure the machine your due is another story but the money is gone.
I came close to entering into an agreement like this with a guy in Florida. Supposed wonderful reputation. Lots of people know him and some high profile people on here vouch for him. I did not go through with it as I could not risk it. These stories make me grateful I did not.
I wish you well and hope that you can achieve some type of resolution. Tough for sure!
