My oldest account is a Capital One Business card that reports as a normal TL. It had some type of old reward structure on it that wasn't competitive so I wanted to get itchanged. The regular CSR couldn't figure out how to do it because it's too old I guess, but I spoke with someone at the EO and they changed it to a 1.5% with no AF Spark Cash - basically just like a Quicksilver from the personal side.
This card has a twisted and interesting history, and since its my oldest card I definitely don't want to close it. For about 5-6 years, this account was actually open with a $500 limit but Cap One declined to issue a card for it so it just sat there. A couple of years ago, they honored my request to have a card issued and a few months ago I got a CLI to $1500. The card has sentimental value because it's been with me through the tough times, so very glad it's got some new life.
Interesting story. Congrats on the PC
