Now this is very strange to have a level 62 DK and have him jump to 80. I had many of my account(s) hacked into and retrieved many times. Every time this has never happened. Are you sure the person that hacked your account did not level him to 80? If you contact the GM about getting your items back from your 73 and 42 they will get that going, they shouldn't re-investigate your level 72 DK. I know your pain about the GM's, they take so dang long.
