Unauthorized M#MACANDTHING Transaction - Shein/Temu???

Appalling service from Standard Bank recently! I am an unemployed student, I had a small sum of money come into my account on 07/02/25 and on the same day, an unauthorized transaction went through without my knowledge or approval??

I only came to know on Monday, 10th Feb 2025 when I logged onto my app. The transaction went through as M#MACANDTHIN5196** and the last 4 digits of my card. To say I was shocked is an understatement! My account is now deficit due to this transaction that is not mine. I immediately called the call center as this was NOT my transaction and spoke to a bored/amused Rethabile who said that the transaction fell under Shein/Temu - I haven't ordered anything online since November 2024! I am broke! She then said since I am adamant that this was not my purchase, she is going to block the card and notify ***** division whilst I held on the line. When she came back on the line, she was laughing and said to me that ***** division says it is a "system glitch" and that the money would be refunded to my account and therefore she has also unblocked my card. When googling the transaction, "M#MACANDTHIN", it brings up articles of ****s and unauthorized bank transactions. So, is Standard Bank telling the truth? Because someone did indeed just help themselves to MY money for their own online transaction from Shein/Temu and Standard Bank allowed it without my approval! I asked Rethabile how many days it would take for the monies to be reversed, she did not know?? Today is the 18th of February and nothing has happened. My account is still deficit. I am afraid to even deposit any monies into my own account to pay for a few expenses, in case Standard Bank allows any other unauthorized transactions. I feel like closing this account now because it seems that Standard Bank does not offer any security to its customers. It is ****** scary! They seem to find small, unemployed people like me amusing. If I had the time and transport, I would walk into a branch right now.
