How to handle this situation with Abu

Long story short.

I bought a Toro 50 off Craigslist.
Reel felt good, guy seemed honest.

Had to send another reel in, figured I'd send my Toro in for service since the drag felt a little sticky.
Other than that, Toro worked great.

Abu emails me back, reel is too corroded to fix.
I call guy from CL, no help.

I get reel back from Abu, and it's completely non-operational. It doesn't engage out of free spool, the thumb piece is just wobbeling around.

I understand that if it's as bad as they say it was taking it apart could potentially ruin its integrity, but the reel worked just fine when I sent it out. I would expect it to come back in the same condition in which I sent it out.

How should I go about this, do I have a case?
