My credit score took a huge hit from miscommunication. I'm a member of Costco who used Amex until last year and switched to Citibank.
Although I never used Amex for transactions, it was used by Costco for automatic membership renewal. I had alerts setup for Amex and paid my renewal in a timely manner. When Costco switched to Citi, I did not receive a card and it was not activated. Costco charged Citi for my membership renewal and I did not receive payment due notice from Citi. Five months later, my credit score has taken a huge hit. I called up Citi who understood the miscommunication and they waived my late fee. I settled the remaining balance.
Does late fee waiver mean my credit report and score will be corrected? Citi call center rep had a wishy-washy answer. I have also subscribed to credit report to see how it goes. Just asking here to check if there is anything that I might have missed that I should do immediately.
