I married(In community of property) for Since 2012 and my wife has been permanent since 1st April 2015 & submitted all our documentation to the branch, yet I am still being charged the normal client rate, instead of a staff rate on my cheque account...20th REQUEST, PLEASE PAY BACK ALL MY INTEREST FEES AS WELL AS ADDITIONAL FEES CHARGED ON MY CHEQUE ACCOUNT...The personal loans account is even more of a nightmare,Standard Bank Stopped debiting my account for no good reason, for months and months, and when I found out I had to load my own stop order, I have asked them to adjust the arrears amounts to the loan terms & still nothing has happened, I am tired of calling the personal loan and check call centre as I get no joy and I have never received a phone call or follow up with regards to my query, I DO NOT KNOW WHAT TO DO, CAN ANYONE PLEASE HELP
