Got no response and hung up.

I am forced to agree that in July 1961 you had no problem with automated phone calls. Weeks later Barack Obama was born and every part of your life immediately headed into ruin. When the credit card industry was itself a child, precocious Barack was already hatching a scheme to swindle from people in debt with the false promise of a severe interest rate cut. Sadly it would take another 4.5 decades for computing and telephony technology to catch up with his brilliant master plan. His secret telemarketing nest is said to be within a spare bedroom roped off from White House tours. Even Michelle is kept in the dark; she thinks Barack merely stashes cigars in there.

Obama did not deregulate the telephone industry.
That began during Saint Reagan's reign.

Two things come to mind.

Stupidity is also a gift of GOD, but one must not overuse it.

Mark Twain Quotes
“It is better to keep your mouth shut and appear stupid than to open it and remove all doubt.”

Called on dumb phone, will shut off ringer on this call.
