AHS - American Home Shield deceptive attempt to snare me into setting up an account Carroll, Iowa

I was home on a Wednesday recovering from a foot surgery. The phone rang and the caller announced that I "need to renew"
my American Shield Home Warranty account. I told him that I wasn't aware that I had such an account. He said "Oh yes, you do, and I
sure hope that you haven't had any expenses for things that were covered, like your water heater, furnace ..." etc. So I told him
that I would prefer to lookup my account online.  he gave the web-site address. To make a long story short, it turns out that
I have no account with them, and they were just trying to scare me into setting one up.
