hehe, when I worked for Boost Mobile/Nextel we always had people calling in
Them: "I canceled this phone last year, I want a refund"
To which my response was "Well, I don't see anything on your account indicating a cancelation, and due to our non-refund policy I am unable to refund any time on the account; why haven't you called in to dispute charges earlier?"
Them: "Well, I don't check my bank account all the time"
Or, how about the chick I heard on "Handle on the Law" where there was 200k missing from their bank account because they didn't have good accounting practices :x...
I <3 people hehe
