Multiple payments on one vehicle

They refuse to make forced cancellations on previous owners if they can't get hold of them, but rather do what they call forced suspension so they can receive payments from different customers. Ntombenhle Mdlophi was very unhelpful as she insisted that I must take another 36-month contract instead of continuing with the previous one. She said it's company policy to keep other clients paying for cars they no longer own and have multiple people paying for the same vehicle. My car now has two units, which harms its battery life. They are refusing to remove one so they can keep milking us.
