I constantly get calls as well. I love the one from "The Department of Visa-Mastercard" Yeah. Right!
Also the calls from the Pakistani/Indian fellow, representing "Medicare", who can never pronounce my name. Medicare has only ever contacted me by USPS, and sometimes via email, only directing me to log into my actual online account
There are other interesting callers, but my responses normally vary.
"Please restate your name, phone number, your company name and address, for my recording of this call"
"Due to very high caller activity, please clearly state your name and call back number, and I will return this call in the order that it was received.'
"Please restate the name of the party that you are calling, your name, phone number, and company name, and please hold, while I try to reconnect you."
I have others, but normally, the line goes dead quite quickly.
