I WANT MY MONEY BACK

I have been de*****ed and FNB is telling me that I de*****ed myself. Someone has been using my account for Bolt, Refinery, PAYFAST*Shara Hai and Spotify. I woke up at 5am to a message from FNB that my account was overdrawn (I don't get in contact messages and I had no reason to keep checking the app for transactions) . I checked my app and all my hard earned money was gone. My account was on - R1475. I immediately logged a ***** on the app and my card was blocked. After a week I called to follow up but the ***** case was not logged and my account was now on - R1600. The Lady assisted and I told her all the transactions that I was not aware of. After 2 weeks with no feedback I called again, I could not get someone over the line. I called twice, when someone finally answers the line drops (after waiting for +-25 minutes with each call. I then opted for the secure chat. The guy that assisted me only refunded me for the bolt services and told me that I received an otp pin on my cellphone for all the other transactions. Why am I only refunded for Bolt services and the large transactions are not refunded? When I shop online, I get directed to the app to authorize a transaction, now I am being told that I received otp pins- since when does FNB send otp pins for online transactions? I want my hard earned money back, I want the overdrawn amount as well because it was not my fault that the security of this bank was breached. I trusted FNB with protecting my money. When all of this happened my card and cellphone where with me. My family and I suffered until I got paid again by my employer just because FNB failed to protect my money and now you are telling me that I will not get my money back...
