Unhappy client

I sold my car on WeBuyCars Brackenfell branch, I requested to take my number plates and disc card with me as I sold them the car not my personal information. The buyer assured me that they will take them out and will not sell the car with my number plates and disc card. I saw the car I sold to them and it had the same number plate and disc. I’m not happy with WeBuyCars. How can you sell the car with my information? Who is going to pay for traffic fees if the person you sold the car has disobey the traffic road or is fined? When I sold my car to your branch, I had no fines or anything. I wrote to your Facebook inbox to sort this mess out and I will involve the 3rd party now because I told you the very same day I stole my car to your company that I want to take my disc and number plate. You bought the car and it belongs to you so take my number plates and disc out of that car.
