I have a private unlisted phone number with Verizon,and I am very careful who I give my phone number to. I do not let any business etc have the number. Well one day my caller ID showed MCI was calling, so I answered and asked them how they got my phone number and they could not answer my question. This happened one other time on another unlisted line with a phone company. Somehow MCI obtained my phone number from Verizon despite the fact it is a non published number (unlisted).
What do you think ?
