Unsolicited calls on my unlisted cell phone number. Callers only speak Spanish and will hang up if you speak English. Calls come from Boone, Kentucky (I am in San Diego, CA); cannot figure out who or why they are calling. If you try to dial back, they are either busy or will hang up if you speak English.
The same stuff happens to me. I don't how these guys got my number but it is starting to piss me off. Watch out, I haven't called these guys back because I don't want to be one of these people who gets scamed.
