DIFFICULT PROBLEM WITH A REPAIR SERVICE-

I sent off a Teac R to Reel (a 35-2B) to  guy near Chicago to refurbish. It had originally sold for $1700 when it was new, and it had a lot of useful features, including direct outs to an external preamp from the playback heads. When he dragged his feet fixing a part I sent him ANOTHER preamp unit I found on Ebay with a working switch.  Then he complained the machine had some distortion on playback and couldn't find the source. Initially I told him to try to sell the machine and give me a partial refund but he never even tried. This guy claims he has a 200 machine backlog (!)
In the past he did fix 3 Teacs for me of a newer vintage and they all came back working like new. He took his sweet time (of course) but I tried to be patient, etc. But THIS time around Dr.Jekyl turned into Mr. Hyde and no matter how many complements I gave him, PLUS a $300 deposit as an incentive, he is (now) the nastiest creep you can imagine.
So I told him to put the machine in a box, send me a invoice, and ship it to a really top-notch repair guy I discovered not far from where he lives. I've been reminding him for the last SIX MONTHS to do this, and STILL I can't get him off his lazy butt to do this. I just hate to see this super-nice machine gathering dust halfway across the country from me.
PLUS (OF COURSE) it belongs to me, not him. But since I "kept changing my mind" (only once but he's completely irrational) he is now not even answering my emails. I'm not an attorney, but I would like to make this person do what I requested and do it NOW. I ALSO would like to put a big dent in his reputation without using facebook. Any suggestions would be appreciated. Thank you. ALSO- Happy Easter and Passover.
