3 year business account declined

So I've been banking with Standard bank business for 3 years i have a card machine from them as well. Today being the first time ever applying for a loan from them as i will be expanding and have signed a new store lease . My banker whom i can never get a hold of never advises anything basically never hear from her has been advising me for months to just get my financials and she will action my application, whenever i asked what do i need to apply. Well low and behold my accountant gives her everything for her to say delclined.

Well thank you Standard bank for wasting 3 years with you guys for giving me a higher rate than other banks on my card machine as well.as.my account and then declining me when i've signed a lease thinking my bank will support me the way i have supported them.

Whats worse is my banker calling me all cheerful and happy asking me to close my account which i requested after being declined but no one even trying to assist a small female business owner. To ask why are you closing the account ? Let us trying and different loan? Nothing just a cheerful call asking for details to close account. Absolutely pathetic service in branch or over the phone . just take take take yet when we ask for support nothing!!! Its fine ill go to another bank.

Thanks guys for nothing
