This might be pretty obvious, but I'm gonna ask anyway because disputing one thing at a time is taking far too long. What if I have 4 accounts to dispute with the same company (Citibank)? Should I submit them all at once and hope for the best, or is it more likely that all 4 will come back verified?
One option would be to dispute 1 Citibank account along with 2 or 3 other items you're looking to place in dispute. That way you're not slamming Citi with disputes on all 4 accounts, thus giving them a reason to just verify everything at one shot, and also you're not only disputing 1 item at a time.
