I received a letter from Penn Credit Collection agency dated XXXX XXXX, XXXX. 
The letter saying I owed {$56.00} for a parking ticket ( XXXX ) from XXXX XXXX, XXXX to the city of XXXX. 

I had paid the ticket in full in XXXX XXXX to a collection agency called XXXX XXXX XXXX, XXXX with USPS money order ( receipt number XXXX ) in the amount of {$56.00}. 

The amount I paid in XXXX is {$56.00} is the same ticket number XXXX from XXXX XXXX. 

I am not sure why Penn Credit is trying to make me pay for a ticket I 've paid for almost three years ago in full.
