Product: Credit card or prepaid card

When I opened the US Bank account I charged an item. I never received a statement or payment request. I sent in {$35.00} anyway. They sent me late fee charge. I complained and they reversed the charge. Their 1st they came back with a late fee-weird. They never sent me paperwork for bills/min. payment so I continued to send {$35.00} per month. 
I transferred credit card funds from another card. They were suppose to give me a year before any interest, they violated that & again no paperwork that they implemented the transfer early. All of a sudden they are saying I owe them over {$500.00} and created all these false charges and late fees. My debt went from XXXX to XXXX. I submitted a XXXX complaint. They tried to intimidate me with sending books of paper, more than 50 pages at a time saying I owe them all this money. This is onlyXXXX I have no other cards and have a XXXX credit score. Then they attacked my credit score 1st took it down to XXXX then attacked it again so it is now XXXX without consulting me or communicating with me. I've have had my home over 37 years, I pay all my bills. This company is not sane. After fighting for months they sent a paper if you pay {$76.00} per month we will only charge 4 %, I accepted that but they kept sending books of papers with different amounts of over {$500.00} per months required. I told them I will not be intimidated. They have violated this before and penalized by you. Looks like they continue the same practice to intimidate smaller customers. I have no other bills or companies that would impact my credit score, all bills are paid on time Government Action : XXXX  reports on known government actions involving business marketplace conduct : : CFPB Consent Order On XX/XX/XXXX, the business entered into a settlement with the Consumer Financial Protection Bureau ( CFPB ).
