Hmm, am I suspicious?

Got an interesting phone call (on the land line, being as I'm at home waiting for the cue to take off for Kirkwood for the ski weekend). Recorded message saying they've been trying to get ahold of me about lowering my credit card interest rate and would I press "1" to speak to an agent or press "2" to decline the offer. What the heck; pressed 1. Live person comes on the line and asks if I'm calling about the interest-lowering offer. I say, "Yes, but first I'd like to get some confirmation that you actually are my financial institution and this isn't a scam." (I have, in the mean time, realized that the recorded message never actually mentioned the name of my financial institution.) Sounds occur that might be a call being switched. Long silence. Dead line. So ... you suppose maybe it was a scam? (This is meant to be a silly rhetorical question with an obvious positive answer.) Y'all practice safe phoning out there.
