Have you try to email the customer service instead of calling them? As many of you, my experience with the MCI customer service over the phone is not good. When they didn't credit me with the right number of mile for the "25K Win-Back" offer, I email them using the form in the Online Account Manager. A few days later, I received a nice apology email stating that the correct number of miles will be posted shortly. We will see if this will happen but at least this experience is better than the phone run-around.
