No solution from wesbank

I got finance for the car from wesbank, I also added a the warranty. When wesbank sent contract did not send copy of a warranty. Car needs mechanical repairs and don't know what I am covered for. I called wesbank, they advised me to call a dealer to get a copy and I did call a dealer, dealer said wesbank should give me the copy. Now I am very tired of this back and forth. I was expecting wesbank to help since I bought the warranty from them. Car needs to be repaired. Very disappointed with the service from wesbank regarding this matter.
