A: I'm calling today about a bill that I never received. B: Can you tell me which credit card it was for? A: It was for my Master Card. B: You should've gotten that bill two weeks ago. A: I haven't got it in the mail yet. B: The computer is showing that all bills have been mailed. A: What am I supposed to do about my bill then? B: Maybe you should call your post office. A: But if it's their mistake, can I get an extension on my bill payment? B: Yes, but you will need to send us proof of their mistake. A: Thank you very much for your help. B: No problem. Enjoy the rest of your day.
