207-433-5421 Calls & hangs up at our business. Even if their automated "put me on the do not call" list process works, it won't for us, as our individual phone calls all show Caller ID for our direct lines, not the main store phone number that gets called in on. Sigh.
Always answer these types of calls - they have to pay for completed call. Keep them talking as long as possible with fake info so they have to pay more.
Robocall claiming to offer free grant money. Pressing 9 to be removed from their calling list just gets you disconnected. Will be filing an FCC complaint seeing as these robocalls are illegal.
