Product: Credit card

Dear Sir, I am writing this complaint as PNC has refused to reverse the unjustified interest on PNC Credit Card despite earlier assurances to do so. 

Background On XX/XX/XXXX, an ACH from PNC hit my Checking account with PNC for payment of my PNC Credit Card. As a consequence my bank account was short of funds which by the nature of my checking account ( XXXX XXXXXXXX ), PNC gave me time till XXXX XXXX XXXXXX/XX/XXXX as per attached email. In lieu of this, I immediately arranged to fund my bank account and on XX/XX/XXXX XXXX AM, my bank account was credited with funds. However, for some inexplicable reasons, PNC contrary to the email sent to me returned the funds. 
Upon realizing this, I immediately tried to make an additional payment to PNC Credit Card though XXXX Banking XXXX facility as the due Date for my PNC Credit Card was XX/XX/XXXX. However, the PNC Website did not permit me to make the transfer as the PNC Credit Card has not posted the reversal and refused to accept payment from me. 
I contacted the Call Center on XX/XX/XXXX and the Call Center Agent could not process the payment at her end either and suggested that I wait for the reversal to be posted. She also assured me that any interest and fees would be reversed. On XX/XX/XXXX, the reversal of credit was posted and therefore, I immediately made the payment through online transfer facility. I contacted PNC call center once again and requested that any fees and interest ne reversed. They again promised to do so as soon as such fees would be levied and clarified that notes were added to my account to do so. 
On XX/XX/XXXX, a check reversal fee of {$27.00} was levied and so I called PNC to reverse these charges, which the agent was able to do so. However, since the interest fee was not levied, she said that she could not reverse it and suggested that I call PNC after the statement was generated. 
After the statement was generated, I saw an interest of {$210.00} for 2 days delay in payment and I immediately called up PNC once again requesting reversal of interest. This time, the agent said that they have already reversed the check return charges of {$27.00} but could not reverse the interest fees and have levied an internal compliant and suggested i follow up for results of the complaint. 
After couple more of follow-ups, I was informed today that PNC has taken a final decision to retain the interest charges. 


In lieu of the above background, I am lodging this complaint to PNC keeping in mind : a ) The circumstances for return of payment by PNC despite funding the account within their stipulated timeframe, b ) PNC restricting my ability to make payments to credit card on XX/XX/XXXX despite my intention and ability to do so. 
c ) The unjustfied interest charges levied, d ) The eggregious amount of interest for a 2 day delay and e ) Their failure to adhere to their commitments/ promises made to me several times by their customer service agents. 

In the event PNC fails to reverse these interest charges, I have decided to exit my relationship with PNC which goes back to XXXX as I do not like to do business with organizations that do not keep their word. 

I request CFPB to address these complaints and prevent further such behaviors. 

Yours truly XXXX XXXX
