Walmart damaged my car and they claimed they recieved the car like that it is not true because they checked the car in front of me and they never let me sign a damaged report they said they checked the camera wolkes barre, Pennsylvania

start i bought a car from a dealer a week ago i drove it 200 miles i decided to change the oil for another car i just got 2 days ago i brought both cars to walmart before they took the cars in  they check the car opened the hood never wrote any damage reports on any of the cars i came back to pick up the car i found on of the macanics driving on of my cars outside when i asked him he said they are allowed to do that and he mention to me there is damaged to the car i asked for the manager she told him you are not allowed to drive the car outside but they are still claiming the damage was there before i brought the car so they had a claim for me through there insurence company but lucky me i bought the part that was damaged and i fixed myself and i had made the call to the insurence agent travis i told him i fixed the car myself and im ok i dont need any money except i need the truth and an apology he answere me right a way i have to deny or claim i told him did i ever ask you for money which is my right to get my car fixed by walmart but i think walmart in this case try to scam people by letting a third party to do there dirty work and now i know and its probably a black and white thing god bless america if they take there dirty people out of it
