Change of DD date

I've been fighting with FNB for exactly a year now. Never have I received such terrible customer servicein my life! I am appalled by the lack of accountability, the lack of efficient agents and outright bad service from FNB. I've been asking for a change in my debit datefor the past3months yet I'm still getting debited on the incorrect date. This is a HUGE inconvinience and NO ONE from FNB is willing tofix this. How can a customer keepasking for the same thing over and over again and it doesn't get done and notes are not left on my account. What kind of a business are you guys running???? RB Jacobs keeps sending people who know nothing my way. Is there no one in FNB who can change a DD date??and I'm not having that it'll be changed after a month cause I've been requesting for the same thing for 3 months!
