I was working tech support for a national ISP/Cable provider. A elderly female customer calls in and I give my typical call opening:
Me: "Thank you for calling _____ may I have your telephone number starting with the area code please?"
Customer: Dials her phone number so all I hear are beeps
Me: "Mam, I need you to TELL me your phone number, you see I am not a machine."
C: "I just typed it in but OK!" and proceeds to dial her number again.
It took me 4 times of back and forth to get her to tell me her number, and then took me ten minuets to find out that there was no problem before she hung up on me.
