Business ProfileforPlus Auto Sales

I purchased a vehicle from this dealership on 10/27/2023 for 6500 using my citibank card for 4000 and 2500 from my discover card. From the minute the purchased were authorized is nothing but lies and deception from these scammers. They sent me pictures of the vehicle not one pictures show and scratches or damage to the vehicle. The pictures of the inside show no indication that many of the buttons from the vehicle had been missing and also the dash board pictures show checked engine light. The vehicle was supposed to arrive in ******** in 3 days it did not arrived until another 3 days later. I had to ker reaching out to transport to verify when the vehicle will arrive. When the vehicle did arrive it was major scratches and dents on the vehicle and the checked engine light was on. I reached out to plus auto and they advised the issue was coming from because the car was lift to put on the trailer for transport. They said to drive for about 30 minutes and it should be move. I drove it , the checked engine sign was still there. I called back and I let him know the issue is still there he said drive it for a few days and see. I drove it for a few days the check engine sign did not come off. I reach back out to plus auto and I was told I need to take it to the dealership to have it reset. After that and I try contact plus auto I get no response. So I file a dispute with both discover and citibank for receiving a product that did not match their description. Citibank found in my favor and issue back the credit, then plus auto came a repossessed the car illegally, refused to give me my property and try to bully me to return the vehicle key. They sent me a letter date 3/19/2024 stating I owe them 7100 which is 6500 for the vehicle and 600 for repossessed fees. My discover card paid these scammers and thieves 2500 and the vehicle was only 6500 so how I owe these thrives 7100, when they have 2500 from discover
