Product: Credit card

A check was sent to the First Bank of Puerto Rico to cover the remaining balance of the credit card. This check was for the total of {$49.00} and it was issued directly from my checking account of XXXX XXXX XXXX. The check was sent to First Bank of Puerto Rico on XXXX XXXX of 2016 and the due date for the payment was XXXX XXXX 2016. I checked the statement on XXXX, XXXX, XXXX, and XXXX and there were no signs of any amount due or overdue for this credit card. There were new charges on those months which were paid off entirely using the same way that it was done with the XXXX XXXX 2016 payment. By XXXX XXXX of the same year, the XXXX XXXX check was already 90 days old and it was n't cashed by First Bank of Puerto Rico. Therefore, XXXX XXXX XXXX put a stop to the check and cancelled it per their bank policy. By XXXX XXXX of the same year First Bank of Puerto Rico attempted to cash the check ( which was already cancelled by XXXX XXXX XXXX more than 2 months back ) and it was unsuccessful. Then, First Bank of Puerto Rico proceeded to threat the amount owed as an overdue/unpaid amount since XXXX XXXX 2016. As a consequence, First Bank of Puerto Rico posted and made two late fee charges from XXXX until XXXX 2016, applied and added corresponding interest rate to those late fee charges and to the owed amount, and lastly reported a delinquency to the credit bureaus for this account. All this, which was posted in the credit card statement by XXXX XXXX, without sending a single communication from First Bank of Puerto Rico to myself about the issue. I found about all this by myself by reviewing the statement that came out by XXXX of 2016 for the credit card. 
As soon as I discovered this I proceeded to contact First Bank of Puerto Rico about it. First Bank acknowledged that they received the check by XXXX XXXX 2016 but they allegedly were not able to cash it due to lack of funds. I opened a case with First Bank to initiate and investigation and they asked for 10 business days to come up with a resolution. Later that same day I contacted XXXX XXXX XXXX to verify the facts about this payments. XXXX XXXX XXXX confirmed that the check had sufficient funds around that period of time for the check to be cashed by First Bank of Puerto Rico. XXXX XXXX XXXX also acknowledged that they had no indications of any attempt by First Bank of Puerto Rico to cash the check and that no check had been returned to them from First Bank due to lack of funds. 
I contacted First Bank of Puerto Rico after the 10 business days of the investigation to find out the resolution for the case. The result was that the check could not be cashed due to lack of funds and that the check was cancelled by XXXX XXXX XXXX. I submitted a reconsideration of the case and offered to provide all the documentation from XXXX XXXX XXXX to back up that the account was in good standing ( with sufficient funds ) at the time for the check to be cashed. I gathered and send all the documentation required ( a letter from XXXX XXXX XXXX, a statement from XXXX XXXX XXXX, a letter written by myself explaining the case, etc. ) and gave them another 10 days for a new resolution. The second resolution came back with the same result than the first one, that the account had no funds at the time and that the check was cancelled by XXXX XXXX XXXX and therefore, all charges applied.
