I left this open so the OP could get his point across to the masses, but at this point I think this has run its course. I haven't seen the shop owner in question post in a long time so I doubt he is very active on this site to even reply.
Domestic disputes about money can be handled with the police. There is nothing TR can do for you at this point. If you'd like others to be conscious of your plight, place a tidbit in your signature and post where others can see it. Anything else, PM me.
