FNB is rude and unwilling to help

after complaining to Hello Peter FNB was fast to phone me. FNB said i can not change the debit date of the Debt protection plan. the Debit date will be between the 25th and the 27th of the month. I am very upset cause the only option they gave me is to cancel the product. I am a Platinum Card holder and i am moving my banking to another bank. they are unwilling to help me. When FNB phoned me back the person was very rude to me and I do not want to leave it there
