Extremely bad service Private Banking - Home loan

Due to bad service and service fee I pay for Private Banking I moved to a different account. Private Banking bad service just don't seem to surprise me anymore. I was still with Private Banking when I app**** for my home loan. I want to change my debit order, and I was told by home loans that I have to deal with Private Banking as I was with them when I app****. No surprise that the service is once again pathetic. I have been on the phone 4 times trying to change my debit order with no feedback whatsoever. I pay my service fees every month and expect someone to help me when I need it. The pathetic FNB app is useless and home loans are not even available on a Saturday. Due to this bad service from FNB, the will leave me no choice but to move my home load to a different bank. I will rather go through the admin and apply and move my home loan than to sit with the frustration, where I cannot do a simple change on a debit order.
