Who called from 7205046034

WTH??!?  I just got a call at 9:30 and I called back.  It was on my cell.  There was a rapid message and it said that "it will take 24 hours to take effect"...Cryptic, yes?
UGH, I am going to block the number from my phone.  Too Creepy.

One of series from different numbers over the past 2 1/2 months that come in a test message showing only phone number.

Maya called and asked for owner or manager. Said she was from U.S. Health Exchange and something about comparing health care rates.

720-502-0414 text me. It said to text a different fewer diggit number to activate instagram. Which is weird cause I didn't try to get an account. The address was denver, Colorado

The number was 720-504 not 502 my apologies
