Hacked bank account

My account got hacked by ******** who new my cell number and the fact that I had A Tymebank account. To me that sounds like an inside job or Tymebank was hacked and the neglected to inform their clients to be on the alert. I received an SMS stating their was a problem with a received payment and that I had to log in to my account to clear the problem which I did everything looked normal with Tymebank logo etc and acouple of days later my funds was drawn via a cardless transaction at an ATM and I wasn't even informed of this transaction taking place, I discovered this after I went to fill up on petrol and the transaction was declined and I then logged into my account because the balance on my phone showed I had funds but to my dismay I discovered that the withdrawal took place the day before. I then called in to Tymebank and what a dreadful telephone system they have you can hardly hear the respondent because of the echo and its not the 1st time I encounter this problem. I eventually had to end the call but they at least got the gist of my complaint. I received a case number GFD-19911 and a promise that I would be updated by 12pm 2021/05/03. So far not a word. I tried calling again but the line is bad that you cannot make out head or tail of the response on their side. So I just hung up.
