Pathetic service

I bought a Chevrolet utility through wesbank. Their service is so poor. I bought the car from McCarthy in Pretoria. The dealership was closing so I notified wesbank I didn't get the spare key,I was promised to get it the next day19th September. I called wesbank they gave me Jermaine Brinks number, I called him he referred me to Nicky Van Dyk,who told that my case was week. I then called Jermaine and told him what Nicky told me, then I asked Jermaine to deal with me since I was not happy with Nicky,on the 26/09 I emailed Jermaine and Nicky asking about my spare key I then got an email from Nicky saying he requested a feedback from the dealership. That was the last time I heard from him.on the 10th/11 I texted Jermaine about this issue, he told me to talk to Nicky. Im sitting with a car without a spare key .can someone from Wesbank explain this.
