Before going on vacation, I set my CitiBank credit card online account to pay my amount owed automatically on XXXX XXXX 2015. My bill of XXXX dollars was due the next day on XXXX XXXX 2015. When I returned from vacation on XXXX XXXX, I was shocked to see XXXX emails that had been sent to me on XXXX XXXX 2015 telling me my credit limits on XXXX cards that I hold with Citi had been significantly reduced XXXX XXXX card from XXXX to XXXX and the other from XXXX to XXXX dollars ) and the XXXX had been cancelled all together. I was also charged a XXXX dollar late fee and my APR was increased from XXXX to XXXX on my remaining cards. I called the company to complain about the situation and was basically told there was nothing they could do to help me. The representative did say he would ask them to remove the XXXX dollar late charge and any remark placed on my credit report, but they may or may not help me with that. I 'm sorry that their system was acting crazy when I tried to submit my payment and it might have not went through, but this being the XXXX time I have missed a payment deadline with them I would have expected them to call me ( seeing as they had my cell number already ) or send me an email ( since they apparently had that as well ). I am in disbelief that they could do this to a customer who has never missed a payment and payed more than the minimum amount most of the time for more than XXXX years. So basically, their website was acting up ( kept freezing up ) when I made the payment and I thought it went through and because of my error I triggered a credit downgrade, a huge credit APR increase, a XXXX dollar charge and a possible derogatory remark on my credit statement. By the way, I paid the entire XXXX dollars I was told I had to pay as the new minimum payment on XXXX/XXXX/15 ( the day I returned from vacation and saw the emails ). This from a company that had to be rescued by taxpayers just a few years ago for mismanaging their assets. I do n't think this is fair and it is abusive to consumers. I would appreciate any help that you could provide me. Thank You.
