Maybe try a different store? Corporate policy does allow pm mobile phones, or at least it isn't explicitly excluded for b&m like SAMs club.
Pm to online like amazon does have an explicit exclusion for mobile phones, although they did it for me, and others claimed success as well. At least as of today. The policy may change tomorrow.

Also, ask for a copy of the policy so that you can educate yourself for future purchases. When i asked them, they claimed that they couldn't print it out. Then when I asked them to show it on the computer, they couldn't do that either, but they did pm, after throwing a bunch of excuses at me. If you haven't read my thread yet, it may help you with some rebuttals if they attempt to make false claims.
