<human>: Can you succinctly summarize the text in 1-3 sentences?

Hello. Around this time last year my bank went through a divestiture. I had two credit cards with said bank and while both were set up for automatic payments, one was set up on the bank side, while the other was set up through the credit side. When the divestiture occurred, the one that was set up for automatic online payments  transferred correctly but the one with the auto-draft being performed on the credit card side failed. I am enrolled in paperless so I never got a letter saying my payment was late and did not notice an email. As a result, I didn't notice the account was past due until after a payment was missed. My credit score dropped from the 720s to 620ish as a result of what I can only assume was some sort of bank error. I recognize my own fault for not keeping a closer eye on my credit cards, especially with the divestiture occuring, but is it possible that this type of missed payment could be removed from my credit report? I know I should have probably done something about this sooner, but due to depression I really couldn't see any hope of a positive resolution but I guess I'm starting to do better with that. 
Anyways,
<bot>: can I have a missed payment removed from my credit report if it is the result of a possible bank error during a divestiture?
