Unauthorized Transactional dispute that is dealt with incompentantly

On Saterday 27th November 2021 a card transaction that I did not authorize was made to a facility I have never heard of on that evening. I was in possession of my bank card and my phone, therefore, I do not know how this transaction took place. I only received the notification on the 29th November in the morning that a suspicious transaction has taken place and that is when I called the ***** department for assistance. The case was logged, however, til now, no investigating officer has been assigned to the case. The bank consultant from Mall of Africa stated that the money cannot be reversed because it was not a debit order. The process of reversals from purchasing something and a debit order are completely different. I, however, cannot comprehend why MY money cannot be reversed if it still states "pending" on my account. From my understanding pending means the money has not been banked so why would the bank allow the money to be banked knowing that it is a **** and the account holder has not authorized it to do so. Til this hour, no one has advised how a large amount of money was authorized to be paid to a furniture shop I have never heard of in my entire life. I did not make any approvals. I was not even asked to make any approvals in any sort of way. What do I do going forward, I don't have money, debit orders need to go through. I need to survive I don't have paperwork of some sort to make reference to. All I have is a reference number and hypothetical theories from the bank consultants. This is synonymous to chasing pavements that lead to no where.

This is concerning. This is outrageous. I need assistance as soon as possible.
