Loan to be cancelled at Nedbank no one is assisting after 7 days .

I app**** for a loan at Nedbank , because of the rate and the fact that my fiancé had received some funds from another bank I requested them to cancel the loan , date 23/08/2021 before this date I went to Nedbank on a Saturday before the 23/08/2021 they told me their system is slow account is not created I must contact call center on Monday which I did , I spoke to Leticia , she logged a call and sms me the call reference and advise I must follow up on Wednesday , I followed up around 9 am call center again the told me my query will be resolved in 6 hours , on Thursday my query was not resolved , I went to the branch again I was told my they have logged a call they will contact me on Friday , then on Friday I sent an email no respond , today I call the call center spoke to Sean who could not transfer me to his team leader / manager cause they are not available , no one is calling me in this whole process I am contacting the bank and going to them myself , there is no sense of agency , they don't even know what they doing ,
