On XXXX XXXX, 2015, when I went to my credit card 's website to pay the monthly bill, on the date it was due, the website was down, and I was not able to pay my bill until the next day. This made my payment XXXX day late. 
The credit card company then added a late fee to my XXXX bill. 
In XXXX, I payed the monthly bill on time, paying the minimum amount that would have been due without the late fee, because I believed that the company should not have charged a late fee, when their website had been down at the time that I tried to pay my bill in XXXX. I expected the credit card company to have realized that their website was down, and to drop the late fee. 
Now, the credit card company is claiming that my XXXX payment is past due, because the wrongly assessed late fee is past due. And they are adding XXXX late fees to my XXXX bill. 
My complaint is Twofold : A ) The credit card company charged me a late fee for a bill that I was unable to pay on the due date because their website was down ; B The credit card company is charging me a late fee on a late fee, when I paid the regular minimum amount due on time in XXXX, 2015.
