I applied for a Chase Freedom Unlimited, a Slate, and a Saphire Preferred all on the same day. I was instanly approved for the CFU for 1500 and the other two I got a 30 day message. I got the denials for the Slate and Saphire in the mail stating the reason for denial being I applied for too many cards too soon and they'd like to see some history on the CFU. I have a Chase Freedom and an Unlmited now, so I log in to pay my Chase Freedom, and I see my available credit is 4500 more than what I had yesterday. I was confused and had to take a double take thinking I was logged on to another one of my cards, but to my happy realization it was on my Freedom. I had my card for the past 2 years now, and this is my first CLI ever, and I didn't even have to ask. Was I supposed to get some sort of letter, or email letting me know?
Looks like they used one of the HP's from the denials to add the increase to that one.
At any rate no they often times don't tell a thing but just do it.
Congratulations on the approval plus the increase with making good anyway on the other HP!
