Disappointed by consultant service at branch

I went to the branch to apply for a credit card, the consultant put in the wrong address for my workplace and also 0000 for the contact number and never even asked me for the correct number, thus the system rejected my application for credit because my 'employer could not be verified'. Despite my efforts to ask for further assistance she just nudged me off with a 'Sorry, you have been declined, there is nothing i can do'. I was disappointed at the lack of adequate explanation and assistance because I do qualify, the employer verification was the only issue, my employer HR department was never even contacted.
