Product: Credit card or prepaid card

Hi, I am a customer of Citigroup Inc. and I have a CITI Mastercard with them. I have a current outstanding balance which I am diligently paying off month by month. I can not do auto pay for my monthly payment as I have very little money in my only bank account and have to be very careful of making the payment in the correct time frame prior to due date when my funds are available in the account I pay from ( a XXXX  checking account ). My method to pay is always the same, I log onto online.citi.com, enter my login and make the payment. This last month the payment was due on XX/XX/XXXX. I tried on XX/XX/XXXX to make my payment. Their payment site was down and this had nothing to do with my computer equipment, as I tried via my cell phone browser too and got the same results. I am working two jobs right now and had to go to work immediately after the failed attempt and then spent the next day working XXXX to XXXX and coming home exhausted forgot about the payment until the morning of XX/XX/XXXX. I made the payment successfully then and messaged them via their website asking for a waiver on the late fee. Here 's what I wrote : " on XX/XX/XXXX I tried in vain 17 times to make my payment online as I always do. Everytime I got this error : XXXX XXXX  Server Error - Generic Exception/URL denied - Citibank online.citi.com I tried different internet browsers, nothing worked your site was down.. I couldn't get back to my computer to XX/XX/XXXX when finally I got through and was able to make payment. I dont want to be charged a late fee for this. Please make an adjustment. I can not do auto pay, long story. Thank you for your attention to this matter.

To avoid late fees, please ensure your payments are mailed 7 to 10 days in advance of the payment due date.

'' I am tired of answers where the answer doesn't even take into account anything I wrote in my explanation or accept any responsibility for their failure. At worst it could be a 50/50 settlement on the issue, but no they just charge the {$27.00} late fee : " XXXX XXXX, XXXX LATE FEE - XXXX PAYMENT PAST DUE Expand Details {$27.00} '' They don't want to listen to any reason or explanation they just charge you the money and place the blame on me. I think this is unfair. 

Recently they charged me interest on my yearly membership fee, saying the membership fee itself was considered a purchase. How can that be? They call it : " XXXX. XXXX, XXXX INTEREST CHARGED TO STANDARD PURCH Expand Details '' and they charge me two months in a row for this. The amount is small, but when I think they do this to 10 million customers they reap huge rewards. Once again I find this highly unfair. 

I hope you can help me with this matter. 

Thank you, XXXX XXXX XXXX
