Priceline complaint: Cleanness of car

On June 3 2022 around 11:30 am, my mother drove me to picked up the rental car from Green motion car and can rental on1601 Airline Dr in Kenner Louisiana. My mother waited in her van outside the business.
After completing paperwork.
I was then handed the keys to a Grey Nissan Sentra. No employer came out to inspect the inside or outside of the car with me.( my mother witnessed this).
Upon returning the car a week later, an employer did not inspect the outside of the car with me. He however did inspect the front inside of the car. The gentlemen opened the drivers door and immediately went to the pouch under the shift with something in his hand and he said we will have to charge for smoking I said I do not smoke and nobody was in the car with me.
He said that looks like ashes to me I then proceed to tell him againi do not smoke then the gentle said he will only give me half of my deposits. I then said it was probably there when I rented the car a week ago. He saidno. He did take 150.00 out of my 300.00 deposist.
