Is this right for them to do?

I enlisted in the National Guard, I am currently in the RSP program waiting to go to basic. I've had bronchitis for a couple months, I made it to my drill on saturday, but early Sunday I had to go to the ER for the Bronchitis (Just couldn't breathe and was having severe pains in my chest) while in there I had the doctor call my sergeant and inform them I was in the ER with this problem and wasn't able to make it. They doped me up on some pain killers (I guess it was from coughing so much it was straining the muscles in my chest) when I got home I had my wife call my sergeant to verify I wouldn't get into trouble. I ped out from the pain pills, and at about 8 in the morning I had 5 sergeants knocking at my door (Including the one that the doctor and my wife had spoke with) they said they where going to turn me over to the proper authorities, they then handed me a piece of cardboard saying "Broke, please help, god bless, god bless" and basically told me to go stand on the corner. Is this acceptable behavior or what can be done about this really, it seems kind of childish.
