It, "HBW," keeps calling even though I don't answer. Once I did answer the phone and it asked for a stranger. He went quiet when I said it was the wrong number, so it was as SG described. I've also had mysterious "San Antonio" calls like the first poster said. It was probably the same number.
Got a call as described above, identified as HBW on caller ID. Did not identify with a company, but called and asked for the name of one of my children who has not lived here for several years, so I suspect they got ahold of a list of Texas State Drivers License holders. It's the only place that particular kid's name would be showing up. He did not go to school here in Texas so that's the only possibility. If they're scammers, that would explain why they're approaching their scam with auto quotes.
