THey called my business cell phone and they did not respond. I suspect this is a robo call looking for available people to call. I made some call list and have been getting these calls from difference numbers for a few weeks.
I have been receiving calls from this number for a couple of weeks now. When I answer, there is dead silence. I tried calling back several times and it just rings forever without an option to leave a voice-mail or an identifying company name. These calls started after I registered for an online survey.
