But what is the problem? If it is a hardware problem and the phone was advertised as working, simply return it. If you or PPC has not given/input the ESN correctly, it won't work. Did you triple check the ESN? Those 8s and Bs look a lot alike on those little stickers!
I just noticed you got it on CL, so maybe returning it isn't an option like it would be if you had used eBay. So be more detailed about the problem, and maybe somebody here can help.
