Unauthorized charges on my account and refusal to reverse or explain them

I sent a request on errors on my account last week and no one has bothered to contact me or respond to me.

Then yesterday I wake up to an unknown negative balance that changed overnight and spoke to an online consultant who can’t clarify why my account is in arrears of over R2000 overnight yet I haven’t used my card in weeks.

I’m started to get really annoying with FNB and these endless mysterious charges on all my accounts. The service via the FNB app has also become so awful and cumbersome with consultants dropping calls mid conversation for absolutely no reason. Terrible service all around with dishonest banking on FNB’s end.
