I'm getting calls from this number for the past month or so. Sometimes 4-5 times a day. They never leave a message and when I pick the call, all I can hear is an engaged tone. I called the number back and they identified as TeleStar Marketing calling on behalf of Comcast. I left a message and hopefully they won't call me back.
Here's the details I got from the net about this company.
Comcast is one of their clients and they specialize in direct marketing and surveys. So I'm pretty sure this is the company. I tried to call the 800 number listed and I got the message that I cannot call this number from my area.
