Who called from 8473421312

This unknown number was txted to me with the word (Alert) in front of it. I did not call back. I googled it and the number supposedly belongs to two people who live at the same address in Buffalo Grove Illinois.Their names appear to be eastern European.

I received the same text alert.  I attempted to call twice and both those got a busy signal so I won't be calling again.

I got a text message from [email protected] saying (Call 1.847.342.1312 -  AC ALERT)
I did not call.
