Query: Problems with audio CDs

My 321 (since returned) skipped while playing several factory audio CDs that are in mint condition and work on every other CD player, including Bose. I tried the same CDs on the store 321 unit and they skipped there too. I then tried them on their other units and they worked fine. I received nothing but "I have no answer" from the store staff. Poor quality for [the money] and even poorer customer service.
