I wanted to share an experience I had recently with Chase. I had applied for a Chase card and was denied due to 5/24, which didn't make any sense to me because I should only have been 4/24. I rec'd a copy of my credit report from freecreditreport.com (thanks
@miztressuz for that tip) and it turns out they were counting a CIP card from 2019. This didn't make a lot of sense to me, so I called and spoke with a Chase credit specialist who explained that it was because that CIP had been past due for 3 months (last year) then it was reported as an account on my personal credit account.
The reason that card was past due for 3 months was because I had closed it when the AF was due (was going to pc it but I had reduced the CL and didn't leave enough to PC to another Ink card) and there was a small balance ($65 or so) on the card at the time.) The account disappeared from my Chase biz login, so I lost track of it and didn't realize there was a balance. For some reason I had chosen electronic statements instead of my usual paper statements, and so I didn't get those statements in the mail to alert me that there was a balance. I only realized it when I got a call from Chase about it. They ended up removing the late fees and I only paid the original amount plus a small amount if interest.
I fully accept I made a big mistake with this situation in not tracking better that there was a balance and not paying it before closing the card. I also am thinking about signing up for some type of budgeting site that pulls all of your balances into one place (that's a thing, right? Any suggestions on that are appreciated). But I also always pay my cards on time and thought I was being careful and doing the right things along the way, so I wanted to share this situation as a reminder to be extra careful and diligent in checking balances and payments.
Sorry for the super long post, but I hope this helps prevent issues for other people in the future!
