Unfulfilled loan agreement

I would like to lay a formal complaint against one of your employees at the Durban branch where I went and filled an application for a loan amounting to R500.00 on the 20th of January 2020 where i signed all required documents and provided my card details for the debit order to go through my account on the 25th of this month however to date i have not received any funds, I was advised on the day I signed the contract that funds will not reflect immediately but will reflect the following day which is the 21st of January 2020 on a Tuesday. I called again on the 22nd of January 2020 at 08:00 to find out why the funds were not reflecting in my account and was advised to call back again after an hour they will investigate the matter. I called at 09:21 in the morning and was provided with an apology and was told that it was a mistake from back office the funds will reflect later during the day. I have knocked off from my workplace, I am sitting stuck with no means of going back home as i was expecting funds to reflect in my account which has not happened. Kindly assist as I would like this matter escalated as I have been inconvenienced and feel that I was **** to and promised something that was non existent. I would like something to be done with the employee and I would like the interest on my loan reviewed as the funds were not received in time moreover should nothing be done with this case I intend on taking further steps so the rights of other consumers are not infringed the way mine have.
