Dear officer, I made a purchase of a really small amount on my credit card XX/XX/XXXX. The bank failed to send the monthly statement by mail and so I was not aware of the balance on the credit card. I did not make any other purchase on that card since then. The credit card company never contacted me about the past due until XXXX months later when I was warned by the credit score change ( 800+ to 620 ) from another credit card company. The bank have all my contact information on file including email address and phone number but obviously they did not try to let me know about the problem. I think the bank should be responsible for providing the account information to me and warn me about past due. Thanks!
