Unhappy Client

I'm very disappointed with the service I recently received from FNB Bank. The harassment and explanation from big bank like this is very shocking. I recently got transactions that went off my account off which I know nothing about, which took my last money from my account which was meant to assist kids with their school staff. I went to report this matter to the branch, and they told me I need to wait about 21days for this matter to be resolved. It really shocked me, and I don't understand what happened to a sense of urgency when dealing with clients matters. On top of that, they left my account with a negative balance, the question who authorized FNB to give an overdraft of so much money, off I never aggred to and never used that for the past 5years I have being with the bank. What the hell is going on with big bank like FNB mis- treating clients and doing as they please, especially when we trust them with our funds. FNB, you really don't take your clients seriously. I'm shocked and disappointed with the current situation.
