Bidvest bank not respecting customers

I have an Old Mutual account which is administered through Bidvest bank. On Saturday the 24th February 2024 I accessed my account twice to transfer funds and to make payment to another account. I believe that I received three login sms when I only logged in twice. As such I went to my microsoft account and had noted that there was a third party account linked to my private email. I lodged a complaint with old mutual bank to confirm how many times did I access my accounts on Saturday the 24th of February 2024 and from what IP addresses as I always delete login notifications. Bidvest Bank then came back to me saying they could not pick up any activity on my account on the 24th of February which is factually incorrect as my statements show that I transferred monies on that day and although payment only reflected on the 26th of February which I made payment on the 24th, there are clear transactions reflecting on my statements. Although no monies were missing how does a bank deny something when there is evidence to refute their version of events. What happens in the event of ***** taking place, is our monies left to the care of *********** people who cannot do something so simple as to just confirm how many times was an account accessed and what were the IP addresses. Bidvest Bank you have 30 days from today to resolve this matter before it goes to the Ombudsman.
