BAD SERVICE FROM FNB

I'm so angry with FNB right now for just deducting money from my account with no warning and no communication or arrangement from them. Money was paid into my account this morning for me to take my husband out for his birthday today and FNB took money from that deposit and now I've got nothing left to take my husband out for his birthday. If FNB had made contact with me about payment arrangements then I would have budgeted for this. This is not the first time this has happened. You can't just take money off a person's account for however how much you want and whenever you want without consent or prior arrangements!! Not very nice of you FNB.!!!
