There was a pause (usually and indication of a call center for telemarketing automated calling) and then someone comes on the phone. Asked for me by name and asked me how many miles were on my 2013 Silverado. He said that he was wanting to get my vehicle in for a warranty maintenance check. I asked who he was and was he trying to sell extended warranties ? He said "we do have one for your vehicle you would need to talk to my supervisor". I said just tell me the purpose of your call I do not have time. He said "I told you who we are". At that time I said thanks and goodbye and hung up.
