sold a vcr on CL

buyer messages me today at 10:00 at at night
saying this thing is a piece of F'n Junk
it won't rewind and ate one of my tapes
i hope i don't ever see you
wait until i catch you somewhere
you screwed me intentionally
you better have my money.

i replied back and said it was working when you bought it
i said no need to talk to me that way
and he seen it working was hooked to a tv and i showed him FF & Rew & ejecting a tape.

i would have had no problem giving his money back if he went about it in a different way but using threats saying i screwed him i don't even want the guy around me or at my house again.
