PaceButler Corporation Rip off on purchasing cell phones Oklahoma City, Oklahoma

I have sent cell phones in to Pace Butler several times and everytime I send them my old cell phones that I know are in working condition and on the list of phones they are buying, I end up on the short side of the stick.
This last time was the last straw.  I mailed in 3 phones only expecting to receive $16 but I figured that was better than leaving them in the drawer.  I received a check for $4.00.  I was told the software was corrupt in my blackberry which they should have paid me $12.00 for and my Pantech was a phone they no longer purchased.
I would not send a phone that was not on the list of phones they were purchasing. 
This is the LAST  time I will send phones to this company!
