MCI might wrongfully charge non-customers or former customers a reoccuring fee for their enrollment in MCI's Basic Dial-1 Plan.

Investigation and pending class action lawsuit against MCI on behalf of telephone customers nationwide who were unlawfully billed by MCI, Inc for monthly service charges despite the fact they were not MCI customers.

The class action complaint alleges that MCI assesses the monthly fees directly or through consumers' local phone bills, and asserts claims. MCI enrolled non-customers and former MCI long-distance subscribers without their knowledge or consent in the "Basic Dial-1 Plan" or another MCI calling plan that carries a monthly service fee. In 2002, MCI began charging a $3.00 or $5.00 minimum usage fee (MUF) and a $3.95 monthly recurring fee to consumers who did not have active billing accounts with MCI and whom MCI has no reasonable basis to believe are current MCI customers. The complaint also states that MCI's policy and practice is to reverse, refund, or credit back unauthorized charges only to consumers who threaten to bring legal action, lodge complaints with regulatory authorities, or take other action. Consumers who do not pay the unauthorized charges are turned over to collections agencies.

One consumer was repeatedly assessed monthly service charges by MCI even though she had a different long distance carrier and had terminated MCI service at a former address several years earlier. MCI refused to reverse the unauthorized charges and threatened this consumer with a collections notice for failing to pay. To stop MCI from continuing to bill her without authorization, she was forced to restrict all long-distance service on her telephone line.
