Please read carefully. F*ckin scammer from craigslist . I had posting on Craigslist someone texted me and said he is really interested , so he said that he got Google phone with some special carrier and to accept his phone call I need to press some 2 digit number (in this case it was 70 , may be in your case it will be different). Call came from another phone number and I picked up and pressed 70 because that di*khead asked for. After pressing that 2 numbers robotic voice from phone said  that I just confirmed opening of Google account. So person who is doing this just stealing your sell phone number AND CAN TEXT AND CALL TO ANYONE FROM YOUR NUMBER WITHOUT YOU KNOWING IT
