That sucks. I had something like this happen once but I was the seller (mine would have been buyer cold feet). Had a pin list on CL sold it, Guy contacts me about the same time the pin got picked up. I let him know sorry just sold it, asks if I have any other games for sale. Think about it and say yes I got a so and so I would sell, plays but I haven't waxed or installed new rubbers, but I have them and for $X I will sell it like it is or for $Z if I clean it up and get it ready. He chooses $Z so I go ahead clean it up install what I have already bought. During tear down I find a few more small things so I let the guy know I ordered a few more parts to make it nice. The hole time this guy is texting me and emailing me how excited he is and that him and the kids will play it and so on. Then the day before pickup I get a text can't come tomorrow, some issue with his house. Tell him that’s okay just let me know when you want to come get it, then the next text he backs out but offers to mail me some money for my parts and time. I think about it but never text him back (to pee'd off at the time) and eventually just list it on CL and sell it to someone else. It really wouldn't have bothered me so much if he wouldn't had been texting and emailing me all the time about it when will it be ready and so on. I stuck to my end of the deal and time even bought a few more plastics to make it sharp.
