Male caller identified himself as Ben. Said he was calling "to help" me. Asked if I still owned __gave year & model of my truck__. I told him I didn't give out personal info to strangers on the phone. He said he indicated that I had not extended my warranty and he was going to help me with an extended warranty service. He then said he was "looking at my file___" and I asked "what file?" He refused to answer, tried the same rote line again. I asked again "WHAT file ?" He said I was not allowed to ask questions. I said a couple of words that you don't want posted here, and hung up on him. I know he was a phone saleman, but you don't tell me I am 'not allowed' to ask questions. Especially if you are trying to sell something.
