A few months ago I cancelled my Cingular account, porting my
number to Verizon. I was on a corporate discount, and after I
had paid what I thought was the final bill, I got another bill
showing a $3.93 credit for the corporate discount, which it
turned out was always a month behind. I called Cingular CS and
asked to have a check mailed to me, and was told that because it
was under $10, they would be "absorbing it" as a cost of closing
the account. When I suggested that I should have just waited to
pay my final bill, the CSR agreed that I could have done that.

Anyway, I had been considering sending an extra $6.10 to get the
balance above $10 but never did it. But I kept getting notified
of new bills online, and it still had the credit balance on it.
Much to my surprise, the other day I got a check in the mail
from Cingular for $3.93. I'll be cashing it quickly :-). I'm
pleasantly surprised (not enough to go back to being a Cingular
customer, but I wouldn't say absolutely not anymore).

Moral: don't believe what CSRs tell you, Cingular doesn't
necessarily keep your balance, even if it's under $10.
