Online purchases ***** on my account

I moved from standard bank to fnb 1.5 months ago. Between the 28-5-2021 and 30-5-2021 the transactions was done online on my account. My w/l has been cut du to non payment as my account got emptied out i have no food. fnb phalaborwa branch do have compation and understanding for my situation but they do not have authority to refund me fnb ***** department is yet to contact me after 3 complaints i understand they must do their ivestigations but what about me in the meantime???? for surely there must be someone at fnb that can authorise my refund or is ut just fine that a bank that big can make a client suffer as there security has been bridged i know ***** is every where but without my cardvpin ir otp the transactions was done how is that my fault and why must i suffer surely the can assist me its just a matter of integrity and humanity but it seems that its non exiting at fnb im moving straight back to standard bank.
