When I saw the statement in the mail, I thought, "Great, the meatheads are trying to get their illegitimate money again."
Surprise! They did a "balance adjustment" for my $36.52 on February 24th, and now I owe them nothing. I'm saving this one. I may have actually won this battle. It's only been about 5 months since I switched and stopped using Sprint. Perhaps I will never have to deal with them again. That would be nice.
