5 Star Rating for knowing how to complicate things

I have been a client for almost 30 years. I have made about 40 calls in the last week to FNB spending around 4 hours on call transfer after call transfer. The first issues is still not resolved...my Home Loan. It was settled but a debit order was deducted days later and it is now more than a week that I am waiting for a refund. The latest, trying to change my debit order details for my FNB revolving facility. The number on my statement is incorrect...got transferred to multiple people and finally spend time in an IVR that kept stating 'we value your time and press 1 to hold for the person you are attempting to contact'. After this message replayed about 3 times, the call just ended. Did anyone test the IVR before implementation?? I was even told by one Consultant to go to a branch to change your debit order?? Really FNB?? I am also in the process of closing my accounts with FNB. In a few months my overdraft will be settled and I will happily move along to another bank that value their clients. Could someone let me know what I need to do to change my debit order on the FNB revolving facility so that the debit order will be taken from my new CAPITEC bank account. Simple request really but extremely complex via your multiple contact numbers and IVR 'assistants' that clearly does not work.
