Complaint Review: MCI Worldcom Cellular

I ordered a cell phone plan from MCI via a telemarketer. This scares me. I just got the phone. I am a regular viewer of this site and have always ignored the cell phone reports. I am always interested in the auto repair ripoffs. However, I have noticed there are a ton of MCI Worldcom reports and how they have ripped people off. I hope this doesn't happen to me, but if it does, I will fight tooth and nail to get things right. There has to be something you ripped off consumers can do to get this corrected. Any suggestions, EDitor????
