Someone calls and hang up, I called back, the voicemail box that has not been set up yet. when it rings, the call quickly gets hanged. Once in a while the calls gets picked up by a "welcome to the verizon wireless national payment center, please enter your phone number", most of the time the line sounds occupied. Then it presents the options the refill of activation of a??? (Unknown) phone.
Call came to a private cell number; only six members of immediate family have this number. Clearly the telemarketer is robo-dialing every possible combination
