Who called from 2166723570

This number has called me three times in the last four days - I answered once and the caller hung up. Since it's from my local area code, I'm getting spooked that it might be someone wanting to know if I'm home.  Anyone else getting calls from this number or know if it's a business?  Thanks!

Called my house at 10 pm tonight. Rang the phone then hung up. I am sooooo mad.

If it called at 10 P.m. then it is not a reputable debt collector.
Just blocked the number with my call blocker
and if it turns out to be a known robo caller
you can have it blocked that way too.

Also they called me on the 2nd at 8:38, on the 3rd at 6:25  on the 4th at 2:41
and on the 6th at 5:57    unless you know the caller, don't answer the phone let voice mail pick up
Also get a call block device.

I'm getting calls for this number also (and it isn't in my area code which is 937) so I don't think you have to worry about someone checking on you.
