Yep...same here, this person calls and either sits on the phone for a second and hangs up or just hangs up. When I call back, they pick up the phone, say nothing and then disconnect. They've called probably 7 times since 9 this morning.
Received many calls, with no answer from caller. Wouldn't leave voice mail. Finally spoke with a female who wanted to confirm mailing address for an order we NEVER placed. Then she tried to sell/give info on other items. Told her not interested, and hung up.
