Hi Tess,
I wasn't sure if you were asking for the Cap One address or the Chase address I used. But, just in case, here is the Chase address...
Chase / Bank One Card Services
800 Brooksedge Blvd.
Westerville, OH 43081
This was the address shown on my credit report. Now, I didn't have any luck getting the lates deleted, but I guess it made it to them. I will just keep trying!
Best of luck to you!
