Poor and unacceptable service

I app**** for an african bank loan i think on 07 May 2021 and for the past weeks they keep sending me the above message daily...i have sent them emails and upload on their website with my doccuments many times. I have been getting these messages: African Bank: We require some documents for your credit application. Please submit clear copy/copies of Payslip/salary advice via our App, Internet Banking or by emailing it to ***********. Queries **********. African Bank Auth. FSP Reg NCRCP7638if you not getting my doccs then call me,stop pestering me instead of giving me the help i inquired about...this is efen nonsense. Suddenly i received an offer, i read and confirm mandate. After a couple of minutes my application was rejected, tried getting an explanation but taking too long for agents and transfer to sales department. Till now no explanation. For so long sending documents, and you give me an offer and i accept, then you reject!!!!! this i can not accept, it's unprofessional, we need loans for the reason and quickly. If you can not help just say so from the scratch. Poor service
