Been receiving tons of calls from tons of different numbers, this being one of them. I was stupid and did an online health insurance comparison about 6 months ago, still adding numbers to my block list. I have received calls from hundreds of different numbers since I did that. I can't actually block calls, so I have a contact in my phone that I labeled block list and they go straight to voicemail. It's so bad that I had to turn my ringer off completely! Anyone I want to talk to will text me. Anyways, this number has called me several times and has never left a message. So I assume it is related to the health insurance comparison I did.
