Highly disappointed and changing banks

Fnb played with my emotions,Last week Friday I app**** for a loan on the system,It was declined with no notification,I then called the Saturday to follow up the consultant said it was declined of which i made peace and asked no questions,The Monday 3rd i was called by fnb to say they see i was busy with an application and it was declined due to system errors am i still interested,There i was very happy and proud of fnb at that time ,In my mind i was so happy that my bank has my back We did everything thing with Dorah ,she laid all options on the table for me we went through processes and procedures,accepted terms and conditions told me on The recorded line that i will get a debi check after I accept the funds will br in my account Tuesday the 4th still no funds Called fnb they said it was declined,i got upset requested to speak to the manager the consultant said he would load a query his working remotely i cant speak to one but would load a query, i was called back after 24 hours with no solution the consultant said she sees it was declined, I asked her why , she said she doesn’t know What the hell? I was promised funds, i made plans as it was a need No manager has called, no call recordings received like i had requested Fnb I am once again requesting all call recordings I am not happy with the manner this was handled
