Non-transparent

So FNB has an issue with some of their clients available balance amounts, I am one of them. I did not know this until I had to query money "vanishing" out of my account of which still has not been rectified. I comtacted the Premier Banking messaging service, but to no avail. I was advised by an agent on 15/02/2024 that FNB was aware of this issue (of which they failed to inform their "loyal & precious clients" of this) & that it would be rectified within 24 hours. It's now 51 hours later & the issue has not been resolved... I again reached out to FNB via the Premier Banking, however, time I was sent from pillar to post & what frustrates me is that the last agent I spoke to (Lesego) didn't respond to me from 7:24am until I sent another message at 07:29am to which he responded that he was checking my account/profile details & then at 07:32am ended the conversation that kicked me out of the session without responding to me or providing me with feedback... I've really had enough with this bank!!!
