Capital One Credit Card Complaint

Capital One Credit card department,

Delinquent account California

capital one is hitting me with a 30 day late on my credit report. between -/-/--/-/- i had setup automatic payments via their website. the payments were supposed to come out of my account on the - of every month. for some reason capital one never withdrew the money from my account. Capital one didnt contact me via phone until i was 36 days late. i immediately paid the balance owed. now i have a 30 day late on my credit report if capital one system would hav eworked correctly or they had contacted me prior to the 30 days, this would not be an issue i dont think my credit should be stained because capital one system didnt work properly. at this point capital one has told me there is nothing they can do. i know this to be false. i havent been late on this or any other card in the last 7 years.
