Pathetic Service from all areas within STD Bank!

For two weeks I have been trying to change suretyship on my daughters student loan and not one person ever gets back to me and assists. I have gone into Fourways Crossing and met with Evelyn who said she will hand the issue over to Elsie Matsetla. I have contacted the call centre five times and the call drops and although I ask that they contact me back - no one ever does. I have sent emails to Lindiwe Thendu who is supposed to be my prestige banker but she is more than pathetic in following up on my issues. I have left message for Mr Russel at Rivonia to please call me however he seems to be too busy aswell. Does anyone actually work at Standard Bank?? Should I rather just move all my accounts to FNB?
