Who called from 3034858928

Call from Exempla Lutheren Hospital in Wheat Ridge, Colorado, reminder to pay bill.

Also received a call from 303-485-8928 and there was no responce when I said hello.  We have gotten this exact same call at least 4 other times in the past.  We have never been to Exempla before and no one ever seems to be on the other end.  During business hours today I may call the number back to see what happens.

I called back, waited on hold for about 2 1/2 minutes.  Turned out to be a bill reminder for service 4 months ago.

Called my cell phone and did not identify themselves.  Looking for an employee who worked for my last place of employment but has not worked there for several months.

This is a billing company for lots of different medical providers out of Colorado.
