ive been getting phone calls lately from random numbers, 414-462-5902 909-842-9105 508-535-3491 and when i pick up no one is there. i try to call back and i get an message saying that if you would like to be placed on our do not call list please press 1 now. most of the time its a ladys voice, but had one message that was a mans voice. has anyone else experienced this. i dont want to press 1 due to unknown charging that i might get(paranoid from past emails). the weird thing is that last night i was discussing this with my girlfriend and i was playing around saying that someone is tapping into my phone line. today she got a call from 909-691-9105 and got the same response when she call back and she had never experience this before. does any one have similar events or know what this is?
