Not a CC app, but when i tried opening a Checking account online I was denied due to having a P.O. Box. Which i didn't, hadn't had a P.O. Box in over 15 years. So i went in branch and opened the account. Once she dug around she was able to fix the issue, but even she didn't understand how it happened considering I held the CSP and it had the accurate address listed.
So while an inconvenient glitch, I think you should be fine once it's resolved.
Just got approved!! And a SL that I personally could not believe. Thanks all for easing my nerves. The 10 day wait was worth it. More on that in the approval thread!
