I had a call from this number on Aug 12th. The person asked for me by name, when I told them it was me, they hung up. I tried to call back and got a voicemail box that sounded like an open microphone in a not-so-busy office. One week later I tried redialing the number and got someone who identified the company as Tangence. http://www.tangence.com/
The person on the other end of the phone claimed to know nothing of these practices and would look into in to find out who in their company is doing this.
I received a call today 11/17 asking for an executive, they wanted to know if he still worked there and if he was still the same title. When I asked what the call was in regards to, they hung up. I tried calling back and got a voicemail. I tried calling Tangence (DCF listed the company above) and was unable to reach a human being.
