Interesting update to this: I called the app status line and when entering my ssn the system would just kick me out to the main menu so I kept mashing # and 0 until I was finally routed to someone to whom I explained how I had applied for the card, had sent the verification information, and never got a response. the agent then routed me to the VERIFICATIONS team, who told me they never got the info (even though I took it in to a chase branch). I then informed them that my business had already been issued a card through Chase, and then the agent said he would check on that and put me on hold. When the agent returned, he said he was able to pull up my accounts and was able to verify the ownership of the business, etc. He then immediately stated that my application was now approved with a credit limit of x, and that I should expect to receive both the acceptance letter and the card within a week.

Haven't seen the new account show up online yet which usually happens before they ship the card, so now I'm holding my breath to see if what the agent told me was correct.
