If you can make tax authorities to see if they pay taxes and investigate them. Just file some sort of complain for money wandering or whatever you think will bring their attention to AMT and George  as as a person
Then go to court. Some urgent REAL legal action which will scare them. And they will contact you immediately mark my words. The refund preferable or your miner will be coming shortly.
No matter what we write here they just do not care. T is useless to mention you hav Los your investment already so just as for full refund if you can take this as advise
