Needing some advice here guys. I put my G2 up on CL for sale as I have a few other devices I prefer, an interested buyer emailed and after some back and forth we agreed on a price and met at our local best buy to make the deal. For starters we agreed on $250 and he hands me $249.70 and says he can't find another dollar or .30 cents, I reply whatever man. He takes the phone looks it over, I do a factory restore (mind you the phone is rooted and was/is running a htc desire z rom.) He asks me how to set up wifi, I show him and off he goes. 4 hours later he calls and leaves me a message saying the speaker is inoperable. (I was using the device for the duration of our calls and the speaker worked fine, I also do not know of any water damage that could have occured to it, but then again I bought it used off CL myself) The calls continue, I was in a place where I couldn't answer the phone but he blows it up with threats and all sorts of things. Today the calls continue while im back at work and then emails begin. They claim to have taken it to a repair shop and that the device has water damage causing the speaker to be inoperable. Later on my grandmother calls me and says some lady (the buyers wife) called her looking for me and saying the police were coming to arrest me. Before calling (because im so annoyed at this point) I send an email stating the device was sold as is/where is with no warranty expressed or implied. The calls continue so I answer and now they are threatening taking me to civil court over it. I'm totally blown away as the only way they would have gotten my grandparents information was to start going through the phone book and calling everyone with my last name asking for me. What the hell should I do?
