Dollar Rent A Car

My name is Alan Carr i rented a vehicle from Dollar rental at Cleveland Hopkins airport on Dec 29 i returned it Jan 5. Upon dropping the car off i watched as the lady inspected the vehicle and she told me the car was clean and that i was good to go. Within 2 hours i received a message with my receipt from Dollar and they had charged me a smoking fee in which i do not smoke. Upon calling customer service several times they said they had a picture of the ashes i supposedly left but no one has seen the pictures. My rental number is [protected] i feel i have been racially profiled due to me being African American
