Bad Service

My review of this institution is a very bad experience, and this is my storie. I have a overdraft facility with Standard Bank of R360 000 and my funds going into the bank is more than 1 Million a year, but I had some problems whereby some of my debit orders that I have has been putting it through my account and although I tried to stop them they still were putting them thru, which of course gave me a bad reflection on my account, which I still can understand but my customers are still paying monies into my account and I still am depositing a lot into my account. So I get a call from my business banker who tells me that the creditors decided that they are going to put a reduction plan in place, so I explained to my business banker what has happened and even put on email to them, and did not hear anything from them anymore and did not have an email or telephone call from to say it is excepted or not, but then realized and the end of this month my monies coming in is not available and that they have reduced my overdraft facility without any warning, and for that has put me into a lot of trouble and I don't think a bank should be able to do that unless there is a mutual agreement between the bank and their clients. I therefore will tell all customers of Standard Bank that they must be careful and that they should rather use other banks than use Standard Bank, and sorry just to also mention that I have been a client of them for 10 years.
