They sucks with customer service

On 15/10/2015 I settled my vehicle finance in full. On the 21/10/2015 I app**** for the same private vehicle finance for another vehicle, my application was approved online and then later declined because my credit report is not up to date. I sent wesbank the proof that I don't owe the car anymore but they still want more proof, couldn't they just look into my wesbank account to see that it's closed. I had to call wesbank to get a settlement letter and send it back to them. I also had to call fnb easy plan loans to get a paid up letter to send to Wesbank. I may have missed an opportunity to buy the car I wanted at a good price. They even take their time to respond to emails. After being such a good customer paying my installments on time every month and actually settled the car within 37 months of the 54 months contract. This is the kind of customer service I receive.
