Changing debit order date

I have over 7 Accounts with FNB, I request that they change my debit order dates since I am now getting my salary on a different date, I called FNB on Saturday of 12/02/2017, I spoke to lady and a gentlemen (who said he was a manager), their attitude was soooooo bad, I am surprised that the changes I requested were never made. I then lodged to complaints, I still waiting no one bothered to call me. Today I called again and spoke to Nthabiseng (who was willing to help) but I need a manager, she promised someone will call me back I am still waiting. FNB really sucks, it doesn't matter how loyal you have been, I have been with them for nearly 15 yrs now yet this is the services I get. I cant wait to move my account, but before that the matter of now returned debit order (these debit order are FNB debit order) will have to be reported to the OMBUSDMAN
