No response on my ***** case

I am very disappointed with Standard Bank especially after moving back to them as I thought they are one of the trusted banks in SA. I logged my ***** case on 30th March and submitted everything they needed. I was told this would take up to 6 weeks. The 6 weeks has passed and I still have not received feedback and even when I call them they say someone will call me from investigations with no luck today they tell me they have no turnaround time on online ***** after clearly stating it will take up to 6 weeks. I’m really shattered as I really did trust them and am very disappointed to say the least with someone having had access to transfer money to themselves from my account and Standard Bank failing to deliver or give any sensible response.
