Early payment - Now credit record damaged

<p>I made an early payment on my American Express credit card in December due to getting paid earlier. I got a message from American express that I am a payment overdue. So I called them and they told me because I paid ear**** the payment was allocated for December and not january. So now my credit record at ITC shows I was 30 days in arrears in January although I made a payment for January.</p> <p> </p> <p>It is very clear that this payment was meant for January. So I dont understand why you damaged my credit record now, although you allocated the payment towards December (which already received a payment end of November.). Can you ASAP send an instruction to all credit Beraus to fix this? </p> <p> </p> <p>This is unacceptable! You know very well the payment was meant for the following month.</p> <p> </p> <p>Please fix and email me the update.</p>
