Trying to sell vehicle extended warranty,  Would not answer my questions that tried to get at how she got my number and why she was calling me.  (We bought the car used and bought, and thus had, an extended warranty from a new car dealer.)  She got very "testy" and hung up.  I formed the opinion she was trying to scam me.

Where did she get the three datums: name, phone number, car make and model year, to attempt this over the phone sales attempt?

Suggest we all report this as a Do Not Call violation.  We can at least cause them the trouble of having to drop and replace the number.
