I waited a whole month this time to give'em a call.... and was pretty surprised to hear my stuff went pending. Looks like the guys at BATF got some help after all.
Depending on what time of day you call you'll end up with an automated/answering machine (early morning time before 12pm Eastern time)... or actually catching someone to pick up your call.
Don't forget to butter'em up when your on the line with'em
