BAD CUSTOMER SERVICE FROM NEDBANK

Very bad customer service from Nedbank. I app**** for a personal loan on Saturday the 18th of January 2020, at the N1 City branch, to which the service consultant told me it takes 2-3 working days to process, so I should be approved by the 23rd of January 2020. On Friday the 24th of January 2020 I still did not get any feedback from Nedbank. So I decided to give them a call. I called their customer services to find out what is going on with my loan application, the consultant to me there is a form out standing that I did not date and sign, but I signed all the forms on Saturday the 18th of January 2020. I even got copies of the forms. The customer consultant advised me to go back to the branch I app**** at and to go date and sign the form that was outstanding. I even left a message for the service consultant to give me a call back urgently on Friday. I went back to the branch on Saturday 25th of January 2020, another consultant helped me, she took the copy of the forms that I signed and said I did sign and date the form that was outstanding, she scanned it in and attached it to my online application that was opened at branch level. On Monday the 27th of January 2020 I still had not heard anything from Nedbank. On Tuesday the 28th of January 2020 I called the again to speak to the service consultant that helped me, to which she was not available, I left a message for her to call me back. Another consultant called me back on behalf of her, telling me there is a revised loan application for me. I asked him if the service consultant can give me a call back, to which she did eventually Tuesday afternoon, she emailed me the new contract of the revised loan, I signed and dated it and emailed it back to her on Tuesday afternoon. I waited till Friday to see if the loan was approved, because I still did not receive any feedback. I phoned them this morning 2nd February 2020, asked to speak to the service consultant to which she is not available,left a message to call me urgently. I even got the branch managers number, phoned and she does not even pick up her phone. What else can I do to get a answer about my loan application?????
