This number call me twice but when I answer the call nobody at the end until I heard a busy tone.

Called me too, no message (don't answer #'s I don't know!), then when I tried to call it back....just gave something like a busy signal. These kind of calls are getting annoying, especially coming while I'm at work! Probably some other stupid company trying to see if its a good #, to send all their stupid "cold" sales call too. They can't scam to run up a bill on my phone, it is not a "contract" phone.

received call no response on other end
