NEDBANK IS EXTREMELY ********!!!

I received an sms on the 11/11/2015 stating that my december debit order would go off on the 18/12/2015 and if I didnt agree I should call and change it of which my mother did as she is the bond account holder and I pay the bond monthly out of my account as I am the surity of the account.She was told it had been changed to the 23/12/2015.And this morning what happens??The debit order goes off my account leaving me without a cent.After us following their request this is what happens.I have since then got my bank to reverse the payment of which I will pay via EFT on the 23 DECEMBER AS I INITIALLY TOLD YOU PEOPLE.I will get the call ref number to provide it to whoever decides to call me from NEDBANK. This is an absolute nightmare as I knew I wouldn't have money for the debit today therefore we informed nedbank.
