Who called from 2176884370

I received a call at 1439 CST, as I did not recognize the number, I did not answer it.  No message left.

Called this morning, didn't leave a message.  When I called back I got a recording saying the number is not in service.

got a call, didn't answer, was on other line, phone says it's an "IL, USA" call, they didn't leave a message

I also received a call from 217-688-4370. I live in an area where the area code is 217, but I still didn't answer since the number isn't in my phone.

I called back but received a message saying the number wasn't in service.

Exactly what happened to me!
