That's the only reason I could think of that they wouldn't be calling you. And, to be honest, if they don't want you for that reason, then you probably don't want them, as you'll be getting bypassed for upgrades by people coming in behind you who do have the 121 time.

Plenty of other carriers out there who aren't going to be as concerned about that, as they're not growing the way Piedmont is, but still have decent movement. You'll do better getting on with them sooner than you will waiting for Piedmont to get back to you.
