MCI review: Credit Balance due

MCI has owed me a credit balance in the amount of $8.00 for 11 months now. I have called in the past, was told the check must have gotten lost and that another would be mailed out. Nothing has been received yet. Another time I called and was told to call another number but if I did it right away, no one would be there anyway and that I would have to wait until the next day.

$8.00 isn't much, but it's mine and I want it back.
