To me he is either uninformed or a crook. I lean toward the latter because he was able to tear it apart but doesn't offer to fix it... Tell everyone you can to stay away from him.
Resin color can be anything from white to black, that's right out of the factory fresh bag. All of it is hard/gritty unless it is damaged, usually by chlorine, then it is mushy and clumpy. Resin is a pretty good mechanical filter and the stuff the softener collects is to be backwashed out of the tank during regeneration. The drain line should be dirty, all the stuff the unit has removed from your water goes through it to drain/waste...
