Useless Capitec Debit Date System and Call Centre

I called to get a settlement amount for my outstanding loan but apparently they can't give me that information over the phone and only the branch can. Then when I called to change my debit order date to the first working day of the month since my salary gets paid in after the first they refuse to change it because the system locates it on the last working day of the month. Then they phone me 8 o'clock on a Saturday to notify me the debit didn't go through and every month I have to explain to them it's because they won't change the debit date and my salary will only get paid in after the first, why can't I choose my debit date with capitec bank? Why is it so difficult to settle a loan? But if payment is missed they are quick to call. What is the point of the call centre if you have to go to the branch for everything??
