Received a bill but the car pictured doesn't match...

Received a bill but the car pictured doesn't match the invoice. I've called 3 times & each person says "I see it's the right car. I don't want to go back & forth with you so I'll get a supervisor to call you". I just want to see that it's the right car & I will gladly pay it. It doesn't help me that you can see it. Why can no one just send me a bill with the right car on it?
