Tech said freezing is normal???

[Agscott]

Sprint replaced my touch pro with a touch pro 2 at no cost. My tp2 freezes constantly and doesn't respond. I called tech support who told me that they would replace the phone but it seems like there is nothing wrong with the device and if a technician checked the phone and didn't find anything wrong with it, they would charge me for the phone. I responded asking if constantly freezing was normal. The lady said it is normal for any touch screen phone to freeze. It drives me crazy, it freezes, runs super slow, and I miss calls. What should I do?
