Unacceptable Customer Service

We Tried to change our banking details to make a loan, which we have had an account with Woolworth's for over 10 Years, its taken since Thursday 30/06/2015- CURRENT FOR THEM TO CHANGE OUR BANKING DETAILS. <br> <br> We have had to phone 3-4 times a day be put on hold at least an hour the minimal waiting time on the phone, then also to fax/email and then get told they don't do credit cards, then to send a normal bank account and for them to capture the wrong banking details on. I HAVE HAD ENOUGH !!! And still sitting with no Luck- Ref for all my call are adding up
