This number hasn't stopped calling me ALL DAY on my business Mobile/Cellular phone. They are also harassing my father on his Business Mobile/Cellular phone.
So far, they've called at 10:20am, 12:54pm, 2:59pm, and 3:01pm, Central Time on Wednesday February 15, 2012.
I called the number back and they said they are contacting me for marketing purposes regarding medical coverage or something like that. I hit #1 to be taken off the list at 10:20am but they continued to call until just now, right before I posted this. If they call again, I'll update.
I'm going to file a complaint with the FTC Complaint Wizard: https://www.ftccomplaintassistant.gov/FTC_Wizard.aspx?lang=en
