It seams like they ditched him off, blaming him alone for the theft because he had no 2fa enabled, which is insane, atleast they could track down where the money went and allow him to fight for his money.
Their support is terrible, i can confirm, but never did i expect something like this to happen.
Presuming op is telling the whole truth ofc.
cheers
To be fair it's pretty hard for them to do something. Just think about it, the stolen account has been selling his LTC for CNH, CNH price went up. A lot of people made something on it. I personally made about btc in the ensuing panic. I saw in the btc-e trollbox people boasting about making much more. The thieves could have had several accounts. How do you suppose to go after them?
