ASHBURN, Va. - MCI today announced it is expanding its in-language Local customer service and sales to include Mandarin, Cantonese and Korean.

"MCI is committed to providing the best possible customer service and products to all of our customers.

WHAT IS THE NEIGHBORHOOD?
The Neighborhood built by MCI has dramatically changed the consumer communication industry. The brand's flagship offering, Neighborhood Complete, provides unlimited local and long-distance calling within the U.S., Puerto Rico, and the U.S. Virgin Islands. This means consumers can talk with whomever, whenever, wherever in the U.S., Puerto Rico and the U.S. Virgin Islands for however long, they choose - for the same price every month. Neighborhood Complete also includes five popular calling and messaging features from one company, on one bill for $49.99 - $69.99 per month depending on the state (taxes and surcharges are additional). The entire U.S., Puerto Rico, and the U.S. Virgin Islands effectively become one local calling area and one neighborhood. In addition, consumers may receive unlimited DSL service for just $35.00 more per month, where available, with Neighborhood HiSpeed.

For consumers who make fewer domestic calls, but who want the convenience and flexibility of calling features, the newest addition to the Neighborhood, Neighborhood Preferred, offers unmatched value. With Call Waiting, Caller ID, Three-Way Calling, unlimited local calling and competitive domestic rates included, Neighborhood Preferred gives consumers the options they want with the simplicity of one bill. Neighborhood Preferred costs $18.99-$33.99 per month depending on the state; taxes and surcharges are additional.
