As I can see numbers are the same, so coins are in account owner's wallet. I don't really understand this:
After a thorough check we found that the account does not belong to you and so it has been permanently suspended and no chance of recovery. We also know that you have trespassed on other accounts and also suspended.
We do not give hackers opportunities on our site and we do not accept such attitudes here.
No chance of recovery - If account was hacked then they should return it to original owner, unless it wasn't hacked, OP broke "multiaccounting" rule and they decided to close OP's account, take OP's funds and after scam accusation they sent coins back to that address.
It is hard to say which side is telling the (complete)truth, but if hacking is in question I don't think hacker would came here to complain....
