Received call from someone with a Spanish-sounding accent around 8:30 PM PST. He knew my first name, when I asked him his, he would not respond, but kept asking me how I was, definitely sounded like a call-center environment, selling something, but wouldn't volunteer his company name or why he was calling. I disconnected the call, but he called me back four times in a row after that, not answering my hello, then just calling and hanging up. I've tried searching the number on white pages and did find the area code is in Boulder, CO, so tried through the secretary of state business search, but they don't do phone numbers. Anyone else know this number?
