Name and shame them - Standard Bank

It has happened twice now. I keep a balance of R 20000 in my Cheque account so that I do not pay Acount fees and at the End of January they charged me full fees. I had to go to the bank to sort it out and I was promised it will not happen again. My latest statement arrived and the same thing happened at the end of February. I contact the customer service via Email and I explain the situation. I get an email back, requesting \more information". what more must I tell them? Cant they check my account? It certainly looks like Standard Bank wants to loose my business!"""
