Bank ***** and my loss

I could not access my account via my app for 6 days and as a result I consulted an ABSA branch. After spending three days and 5-6 hours with the branch manager, they came to a conclusion that R70 000 was transferred from my account to another account that was subsequently closed with no trace of an accountholder, and my account was no longer in existence. I find it totally unacceptable that I rely on ABSA to provide safe services and keep my accounts and my money safe, and they failed to do so and leave me with the loss.
