Homeloan department Useless

Dear Standard Bank. I took an advance on my homeloan and got advised that if I have the debit order deducted from a Standard Bank account, I will get a lower interest rate. To get this done, I had to go into a branch 3 times, probably 6 phone calls, 8 emails, 3 forms and another 4 follow ups. Confirmation received it will be deducted from the Standard Bank account. Come the end of the month, not done. Still going off my FNB account, no discount app****. I'm taking my business elsewhere and heaven forbid, I will rather pay more somewhere else than go through all this torture. You can be sure that I will make it my mission this year to let everyone I know not to deal with Standard Bank. Not worth the effort.
