Terrible service

I app**** for an account with Truworths online, and shortly received notification that it was declined with no valid reason.A few days later a call center agent from Truworths called me and said that they have picked up that I have made an attempt to apply online and they would like to assist me , they took down all my information, asked various questions such as my monthly earnings, expenses etc ...the agent then told me the application was approved and gave me a credit limit amount available to spend at any Truworths store immediately.I also received an SMS confirmation that my application was approved and I should go to the nearest store along with my ID document to sign the agreement and I’d beable to shop immediately thereafter.A few days later again I received a call from a call center agent asking when can they expect me at one of the stores to sign the agreement, I also received an sms stipulating the same thing. I took time out of my work day today to go to a Truworths store and when I got there they told me they cannot find the application, the consultant took my ID scanned it and seconds later I suddenly received an sms saying my application was unsuccessful. How is that possible when a call center agent called me and did the application telephonically and assured me that the application was approved.If there was a error made somewhere along the pipelines it is not my problem, this is unacceptable, I want this problem addressed and resolved.
