BS. Somebody there knows what's going on. Google a name of an employee, call up and get their extension, call them direct and act like they should know you "hey Jim, It's Steve, I haven't talked to you in a while! How's business?" And then explAin the situation. Then, and this is critical, ask for help. The h word motivates people.
And don't ask how the wife and kids are. That can be a giveaway if somebody is single or the kids died in a 3D printer accident.
