I have actually had good luck with the VA medical system and ATT. The VA Voc Rehab System is a bit of a joke though, which is real frustrating. TMobile is absolutely horrible as well, at one point in time I owed them 30 odd dollars, and even after I paid it off they sold it to 3 different collection agencies, 5 YEARS LATER. Found this out after i started the process to buy my home. what a pain in the butt. anytime i tried to egt in touch with Tmobile to resolve they told me to get bent and the collection agencies were horrible, as to be expected. It took 4 months to get it taken care of. I also hate Sirius XM. To get them to stop calling you takes an act of God. I spent about 3 months asking them to stop calling, until I started yelling at every one of their reps that called me. 2 months later, they stopped calling. I dont even get the letters anymore, its great.
