Bad customer service, ************ to customers

On Monday 5th of December 2022 it was on Monday, I visited protea gardens FNB, as my son's account had to be removed from my profile to his as he is no more a minor, The person who was assisting us just printed the mini statement and told my son to come the following day and I ask him why can't he do it now, he told us they are closing he doesn't have the access to go back inside. My son went to the branch the following day, he's been sent back for proof of address as they want to open a new account for him, he told them he has the card, he only need to create a profile, he's been sent back. I printed my bank statement as it has the address and sign the form they gave him. Still they told him they can't help him with FNB statement, they need a letter from the stores, he is only 18 years, where is he going to get those letters from stores? I was surprised late today at around 15:11 when three transactions happen on my account R554, 44 times three went out of my account, I suspect the bank statement they took from my son, now I must do up and down to the bank because of this, I trusted fnb but now truly speaking I'm so disappointed, please help hello peter I trust you guys you help me before and it will happen again.
