Disco is one of those lenders we're not used to anymore. They take the time to work with people and work in their best interest as well. Sometimes they're not so clear on what it is that's needed like this previous mismatch issue when it comes to notifications but, I'm sure you'll probably have something show up in the mail eventually. Disco is one of the quickest to convert to a regular card and from there the sky is the limit for the CL. If you take care of each other you won't be disappointed.
Congrats! Welcome to the family.
