MCI have been calling me for the past 6 months telling me that I owe them money. I have never had their service. They did the same thing 4 years ago, and they eventually stopped, now it is getting worst, I am sick and tired of the rude collection agent. They want me to call MCI customer service. I emailed them several times, not a response. What can I do? Where can I report this? Do I have a good case if I get a lawyer?
