Very Disappointed with the service l got from FNB

I had my money deducted from my account and l had no idea who were those people ducting l called FNB to have my money reversed on my account l was told it's an online purchase so they can not do anything about it l should login a ***** complaint of which l did while l was waiting for feed back that l was promised to get with in 5 of which 5 days went by no feedback was provided to me and money was deducted again by the same people my money got deducted three times and FNB did nothing about l have been calling and all they do is to send you from 1 department to another .as far as l know when you doing online purchase you should get a otp pin to comfirm it's you who is doing the purchase but l did not get those and fnb should protect my money l keep my money in the bank so that it will be safe and they don't seem to be taking my complain serious l have been email , calling still nothing happens. I don't care how much money l bring at FNB but l think l deserve to be treated like anyother customer and l believe in business every cent and every customer counts. The consultants are quite to transfer you to the other person without even trying to resolve your issue. FNB l need my issue sorted ,l want my money.
