I am an athlete in every sense of the word. Athlete, martial artist.
You can call me 10 times a day to pay this bill but, I do not owe your company any money.
I paid my bill. Let me speak to your supervisor!
I'm not going to pay this bill. I don't owe you any money. You do what you got to do!
This customer service person doesn't understand that this bill was paid and I am not going to pay it again.
