FNB unpredictable services

I am extremely frustrated and disappointed with the service I am receiving from FNB homelone division. I spent 5days on the phone speaking to *********** staff sending me from one number to another and keeping me on hold for 20min at a time and more. After applying for a Debicheck mandate and successfully accepting the mandate they just canceled it. Now I must spent 5days yet again on the phone with *********** staff to solve a problem that is not supposed to be one. I am truly disappointed in the service. I am at a point where am leaving FNB.

Can someone please contact me that can help me and not send me from one person to another.
