So last August a local TBer asked me if he could borrow my amp because his was still in the shop. We knew a lot of the same people (from my old HS) so I thought it'd be fine. I said sure and he came over my Aunt's house to borrow it, an old Univox hollowbody, and some pedals. He lent me his fretless. Fast-forward to the following October: I get my amp back, finally, and my fx. I gave him his fretless back but the gig bag ripped. I offered to sew it, or replace, and he told me not to worry about it. He said my bass had a bow in the neck and his friend, who works at a local guitar store, would fix it for cheap. We talk about bass stuff on FB for awhile and then I noticed his FB was gone. I thought he deleted it but it turns out he blocked me. Now I've been calling and texting trying to figure out what the story is with my guitar and he won't answer. I send him a message on TB, and he's logged on since, and he won't answer. He lives on Staten Island with me but I'm not sure where. What recourse do I have at this point? I know the tech he's talking about and I know what bands he's in (no shows coming up though to hassle him) What would you do?
