Standard Bank left me stranded

I never experince such a bad service in my life. I would never recommend standard bank to any one infact I would suggest that their customers should go somewhere else for banking because should ***** happen in their account they will be stuck just like me. ********** hacked my account and managed to do more than 20 transactions from both my credit card and cheque account. The bank balance as I speak is minus142 987.00 I reported the matter last Wednesday. They were so quiet until I had to write a review. On Thursday they sent me dispute resolution form that I completed and sent it back. Yesterday I went to the branch to do follow up they put me on the phone I spent 3 hours on phone they transfered me from one person to another and I was not successful. Today I am at the branch again on the phone again transfered from one person to another its been almost 2hours. I am desperate I have no money and currently my bank balance is minus R142 987.00 and I am receiving no help from the bank
