I too have been receiving calls from this number, every day, for the past few days so far. I have even received a call as late as 6pm.
I did try calling back and heard an automated voice and hung my phone up. After that I'm still receiving calls and refuse to answer. I don’t know if I'm dealing with a scam and would rather not risk answering my phone.
I have received 2 calls today (5:01pm & 5:39pm) and I answered both times, but no one says anything. I can hear it pick back up and hang up, like it's trying to get a dial tone, but I stayed on to see if I could hear anything. I heard nothing and it then I lost the line.
