why charge me overdraft when i dont have on my acc

standard bank is *****ing on my accounts no no no this is wrong. First it was the honouring fee last month on the 7th May. It was then reversed on the 18th May because I complaint, on the 25th May I was charged an overdraft again on the 30th May another overdraft charge haibo! what's wrong with you standard bank? I then called the call centre last week on the 4th and explain that I don't have an overdraft and I don't want it, it was confirm that yes its true I don't have an overdraft on my account and they think I was charged because of the honouring fee that I complaint about, so they reversed my money and take it back in a different way. I was promised they will look into this problem its now a week and no response. DOES THIS MEAN IF WE DON'T CHECK OUR STATEMENTS NOW AND AGAIN STANDARD BANK WILL ***** OUR MONEY??????
