Unhappy customer

My name is MJ Serobanyane i app**** for a personal loan on the 13 may 2025 online and I did get any feedback on the status of that account so decided to to call on the status of the loan. I called nedbank to apply through the consultant which I did because there was no feedback on the one online. We did all the documentation , the following day I received an email saying my personal loan was declined , I didn't get feedback from the one on online. I went to another institution and was helped. As I still did not get feedback from the online application I thought it didn't go through. No calls or any forms of communication. On the 19/05/2025 at 14h00 I received a message saying my personal loan has been approved and it will reflect in my account soon. I started to call nedbank to enquire but I was taken pillar to past. The following day I called nedbank to find out about the money that was deposited. I was then advised to return the money which has created a problem of administration charges which I was not told about , I was provided with banking details. I deposited the personal loan money on the 20/05/2025. Now today I'm being told to pay the administration fees and two other installments I'm suppose to pay. All this was caused by their negligence and their failure to communicate effectively with me
