Banking Woes

My son had a checking account with Chase Bank, part of JP Morgan
He died July 2nd.
I went to the bank on July 27th to close out his account.
After waiting 30 minutes for a banker, and another 20 minutes of her processing paperwork, I was told they "can't do anything until it's been 30 days after the date of his death". 
Being in my state of .... shock, I accepted what she told me and left.

August 14, I return to the bank to attempt to close his account (again).  No waiting this time, but all the paperwork needed to be filled out again -- only to be told that there's a hold on the account.
Um... what?
"You people are really something ... you couldn't have told me that before so I could start getting this taken care of ??  I just want to get this completed." I told them.

After I left, I realized that I wasn't in my right mind to ask questions.

Who put the hold on the account???
My son's employer can put a hold on his private banking account?
Or did Chase put the hold on the account? 
They wanted to get one extra month's payment for his account??
Do they really need that $15 ? 

I checked the Chase website, nothing there says anything about waiting 30 days.

My son worked in retail, and there couldn't be that much money in his account. 
I was just trying to do the right thing by closing his account.
They wouldn't tell me a balance; if it was less than $100 I'd walk away; this isn't worth it!

Seriously, this is crazy.  My advice:  make sure there's more than one person authorized on a checking account.  If something happens to one person, write a check for all but $10 and let the bank just close the account themselves and avoid all this hassle. 

PS:  I don't bank at Chase ... never have, and now never will.
