Congratulations!!! I know exactly how you feel.
I think Discover is going on a graduation party spree right now lol. 4 days ago, I got an email from Discover congrats me on refunding my deposit back. Yay!!! Took nearly 18 months for my conversion. But no CLI. No complaining though. Glad to have my $2.5k back.
Then last night, my wife got an email from them for the same thing. And they bumped the CL from $500 to $1.5k. Yay! and the kicker is that her account only been opened since April. So it's only 6 months. She rarely use the card so maybe they like that more than heavily using the card (mine did).
Congratulations!!!.I'm hoping mine doesn't take that long but if it does so be it. Well worth the wait and money back in your pocket.
