transaction went of my account

Good evening. 2 transactions just went off my account and I immediately called the ***** line. Our which I was told that there is no guarantee that I'll get my money back. In top of this Fnb have been charging me for transactions that have supposedly did not go through. I logged a call and still haven't received a call back. Then it's the case where money that has gone missing that fnb claims I have spent. I constantly keep track of my spending. The service is becoming very poor and way to pricey. The call Centre agents are not trained properly as well. You will loose a lot of clients this way. Clean up your act. Don't charge customers unnecessarily and reverse payments that have been reported as **********
