When I am on hold for 20 minutes, being told over and over how important my call is, the last damned thing I want to do when you finally answer the phone and find an overtly hostile John Cole is recite all my account information, address, phone #, social security #, etc. My local bank has figured out to identify who I am just by analyzing what phone number I called from- check into it.
I am then also likely to use colorful language if you make offers to me before addressing the issue about which I called to talk to you.
