Very Poor Service

Hi my name is Brenda writing from my husband account it is very painful and disrespectful after banking with Nedbank for 11 years to be treated so badly. i have be paying my Home Loan faithfully until in September but i make sure i make payment every month now in Nov without my approval i was double debit even though i told them will pay will via EFT and today i spoke with Palesa Lebata who was very rude to me over the phone defending her people with understanding what is called customer service please i want those debit orders reverse back as i never authorize it. Is very unfair to be treated like after 11 years have NEVER has a problem with them but with this first thing on monday am closing my account with Nedbank
