5 of the 12 accounts are all within the last 90 days, You are probably right, that's probably the reason they are holding off. I went on an app spree, got approved so now I'm just sitting.
Honestly, for me, the money was gone a longgg time ago, and I love the discover card. I'm not in any real dire need for it otherwise I would just cancel the card and get the money back. I'm ok to wait a few more months to see if something changes. I've already considered the money that was the deposit as gone so I don't miss it much. Hopefully soon I will get a check in the mail and then I will be extra happy!
