Worst service ever

I've spent the better part of my morning on the phone with the vehicle finance contact center being transferred, referred, and not assisted.

All I want to do is update my dad's vehicle finance account debit details so that you guys can debit my account moving forward. Apparently the account is on a status that does not allow that.

When I'm transfered the next person is also telling me I need to speak to someone else and in most cases it's the department who reffered me to them.

What must I do? Spend another R 120.00 trying to resolve this over the phone? Please assist.
