I'm calling today about a bill that I never received .   Can you tell me which credit card it was for ?   It was for my Master Card .   You should've gotten that bill two weeks ago .   I haven't got it in the mail yet .   The computer is showing that all bills have been mailed .   What am I supposed to do about my bill then ?   Maybe you should call your post office .   But if it's their mistake , can I get an extension on my bill payment ?   Yes , but you will need to send us proof of their mistake .   Okay , thank you very much for your help .   Not a problem . Enjoy the rest of your day .
