Account Declined??

On the 21st of September 2021 I went in store @ Springs Mall to open an account, they told me I should get feedback within 48 hours, if I don't receive feedback I need to go back in store so they could phone head office, I went back in store on the 2nd of September 2021 just to find out they have not submitted my application and I needed to give all details and documents again. I hardly left the store when I received an sms that my application has been declined with ref number ***7. Today I tried to apply online, again I received an sms stating my application has been decline with ref number ***2. This is a shock to me as I have a good credit history, they didn't even phone my employer or do a credit check on me. I tried to phone the customer services but as soon as they answered the call dropped, not from my side. I just want to know why it was rejected as I have submitted all my documents and I pay all my accounts on time.

This is just ridiculous, I most certainly will rate this the worst experience from a retail store.
