Disgusting service

Last month a transaction I didn't approve went through without me approving anything. This week once again another transaction of R200 went through and I don't evens recognize it. Doesn't show a name or where it came from. Called FNB and waited more than 15 minutes to get through to someone and eventually when I was put through to someone she transferred me to another department( Accounts) . After I finally got through and explained my query again the call dropped and nobody bothered to phone me back nor explain what the transaction is for. I am to scared to deposit money into my account because its always disappearing and FNB is not helpful at all. Poor service. The monthly account fee is so expensive but so much nonsense happens with FNB. Very disappointed.
