Female caller trying to sell an extended auto warranty. I told her we were not interested and to not call this number again, to which she replied "Oh, we will. We'll call back." This is a clear violation of FCC do-not-call rules at the very least, and I strongly suspect this is a scammer. The number displayed on the caller ID is not a valid number, and the caller would not identify the company for whom she was calling - both also violations of FCC DNC rules.
