Wrong description of vehicle on contract documents

I bought a car through dealership finance by them. The statement reflects a discrepancy on the description of the car, which could possibly mean that I was quoted on and paying the more expensive car (higher model) while in reality driving lower model. The dealer says they don’t know why Wesbank put that description and Wesbank can’t help me. I only discovered this much later and I want it fixed but the Dealer + Wesbank are sending me from pillar to post, I feel ****med.
