Product: Credit card or prepaid card

I am disputing the validity of the following charges listed below. Here are the facts regarded the late payment charges. 

1 Purchased items totaling {$56.00} in XX/XX/XXXX. 
2. I paid the balance due in full on Sunday XX/XX/XXXX at a Target store. The payment was due on Saturday XX/XX/XXXX. I thought that since the payment was due on a weekend, the payment due date is extended to the following Monday. I do not believe there should not have been a late charge. 

3. On XX/XX/XXXX, I was charged a late fee of {$25.00} and interested of {$1.00}. 
4. I contacted the call center and requested the late fee to be removed. I was connected to a call center was located out of the country and I had a difficult time communicating with representative. I was transferred a few times and then disconnected. After a few calls, I became frustrated and I stopped calling 4. On XX/XX/XXXX, I was charged a minimum fee of {$1.00}, no late fee and no interest. 
5. During this period, I again make several phone calls to the call center in the XXXX. They would not remove the late fee. Again, I had a very difficult time with the call center personal. I would be transferred several times or placed on hold and forgotten. 

6. On XX/XX/XXXX, I was charged another late fee of {$27.00} and a minimum charge of {$1.00}, no late fee and no interest. A total of {$55.00} balance due. This is the first of many violations of the credit card disclosure Act of XXXX, passed by the Federal Reserve Board of the United States. 
7. The act prevents multiple penalty fees based on a single late payment. 
8. In this case, there was only one transaction and that transaction was assessed a late fee in XX/XX/XXXX. The credit card issuer continued to assess late fees based on the same XXXX transaction. 

9. On XX/XX/XXXX, I was charged another late fee of {$38.00} and interest charge of {$1.00}. A total of {$94.00} balance due. This is another violation of the credit card disclosure Act of XXXX, passed by the Federal Reserve Board of the United States. 
10. The act prohibits the issuer from charging fees more than {$25.00}. The act also prohibits the credit card issuer from charging a penalty fees that exceed the dollar amount associated with the violation. 
10. In this case, the total amount of the transaction was {$55.00}, so the penalties can not exceed this amount and the late fee penalty should not have exceeded the {$25.00} limit. 
11. On XX/XX/XXXX, I was charged another late fee of {$38.00} and interest charge of {$1.00}. A total of {$130.00} is the balance due. 
12. I have been informed by the call center that the late penalty fees will continue to be charged each month if the balance is not paid. 
13. I was also informed that I would be sent to collections if the balance is not paid. 
14. I asked if this was Targets policy and I was informed that they do not have to follow Targets policies because they are a separate company and are only contracted with XXXX XXXX. They are XXXX XXXX XXXX and not affiliated with Target. 
15. On XX/XX/XXXX, I was charged another late fee of {$.00} and interest charge of {$0.00}. A total of {$130.00} is the balance due. 
16. On XX/XX/XXXX, I was charged another late fee of {$27.00} and interest charge of {$2.00}. A total of {$160.00} is the balance due. 
17. On XX/XX/XXXX, I was charged another late fee of {$38.00} and interest charge of {$3.00}. A total of {$200.00} is the balance due. 
18. On XX/XX/XXXX, I was charged another late fee of {$38.00} and interest charge of {$4.00}. A total of {$240.00} is the balance due. 

I am requesting the initial late fee and related interest be removed. Upon reviewing my notes, it appears the payment was made timely. The payment was due Saturday XX/XX/XXXX. The representative at the counter was closing her register for the night. I said the payment is due today but since it is a Saturday does it matter if I make the payment the next day. Usually, payment due on a weekend are moved to the following Monday. Believing this was the case, the representative said it would not matter so I made the payment the following day on XXXX XXXX, XXXX. I had no idea that making a payment 1 day after the due date would result in over {$240.00} of charges. 

I also made many attempts to resolve this issue with the call centers located out of the country but they were difficult and would not discuss this issue. I understand why the call centers handled my issue in this manner. They keep transferring your call until you are disconnected or hang up. Surprisingly, there are no records of my calls. 

Additionally, this transaction has affected my FICA score. It has been around XXXX for many years and because of XXXX XXXX XXXX, my score has dropped to XXXX last time I checked. I also request that all penalties be removed and my FICA score be adjusted accordingly. 

Thank You
