BAD SERVICE - STANDARD BANK

I am totally upset and irate with the service I am getting with Standard Bank. I have been a loyal customer for 35 years. Yesterday the 6th Jan 2022, 4 debits went through my account which I have not authorised. I phoned the ***** dept ref *** and logged a call and was told I will have to wait for 7 days for their investigation. This is not good for me. Why did Standard bank not flag this debit and contact me? I am holding Standard bank accountable. We should be protected from these kind of *****. I am going to log a call with the banking Ombudsman.
