I sent another email to the CEO at Cap One and Stephanie, the same girl I talked to last time, called me again. I have had their card like almost 2 years. I made (1) 30 day late while we were in Texas visiting our son, who is in the Army and was injured in Iraq.
The first time I sent the email she called and did raise my CL but she said the my payment was late and they had a responsibility to the integrity of the system to report accurately.
I sent another email this time explaining that I really needed to get that removed and that I knew they had the ability. When she called I once again asked her to reconsider. That I had proven before and after the late that it was a fluke and that it won't happen again. She said she would investigate it further and do some more research and she would "reach out to me" in a few days. She said she understands that there were mitigating circumstances and she would see what she could do..........maybe this time she'll come through for me!
Starting Score: 
Good luck! 
Keep us updated...it's always motivating and encouraging to see others' successes!
Thanks Monkey...I'll give that a shot next....
As far as the CLI...I had tried calling somebody with a middle eastern accent for an increase but to no avail. But when I emailed the CEO (richard.fairbank@capitalone.com) I got Stephanie in Richmond. After I explained about trying to get my late removed she asked if there was anything else I could need and I told her about getting a CLI and she said she would see what she could do...4 days later she called with a no go on the removal but she could increase my CL from $300 - $500.
