Unfair treatment

I had a bad experience with Standard Bank and the way they manage my business overdraft. I had an agreement with my business consultant, to have my overdraft decreased from R200000 to a R100000. This was not honoured, as it was changed to R80000 without my knowledge. At the end of March some of my debit orders failed as a result. I contacted my business consult who said he will attend to this when ge is back from leave. This is unacceptable. I want the head of that deparment to conract me and I want to be reimbursed with the fees for the unpaid debid orders. And then I want my account correct as what was agreed on. If this is not attended to i will have to take it up with the banking ombud. This is not fair treatment.
