Capital One Credit Card Complaint

Capital One Credit card department,

Texas

On - 2016, I spoke with Capital One in regards to my issue. I explained to them that I had issues submitting my payment online, which I thought that the payment went through. I went through my bank statement and notice that it did n't go through. I went on and explained to them that I did n't want it to harm my credit because I am submitting my payment at a later date. I also went into conversing with them, letting them know that I been requested to change my due date on this credit card. I have - credit cards with Capital One. They assured me that this would happen, they would change the date. They assure me that they were not going to report to the credit bureau. They accepted my payment and gave me my confirmation. Now, I am just noticing that they did report my payment as late to the credit bureau. I explained to them over the phone the other day about my credit. They told me that it should n't have been reported and that I would need to get in contact with the credit bureau. I 've gotten in contact with the credit bureau and they told me the only thing I can do is dispute this late payment. I received the dispute and looked at it and saw that Capital One did n't change anything, they kept it the same. The representative assured me that my payments reflected that I made my payments on time but on my credit bureau its showing different. This have drop my credit score tremendously. I am so upset with Capital One and I thought they were suppose to help with your credit. I ca n't believe that the representative are trained to give the wrong information. I wish someone could please fix this issue because I am really upset at this time.
