nedbank not being honest

Hellopeter.I'm writing this report on behalf of my father who's very old and doesn't understand this thing. Right now my father he's very very angry at Nedbank. On the 28january 2016 my father bought a car which was financed by Nedbank. Everything was done and on the contract he got its shows that his instalment will be R2844.61 plus R57 of service fee which is once off thing. that's how he was advised.to his surprise Nedbank deducted R3500.when we find out we are told its for: data dot. Service plan and Warranty. Of which he never agreed to them cause he was never told about this extras.my father hes very old even if someone from the bank called him,im sure they spoke to him in English and they never made sure or even cared if he understood what they were offering him.as a result he might have agreed.my father doesn't want this extras. If anyone from the Nedbank is going to call my dad, please use Sotho/Sepedi language with him and can I please be updated by you Nedbank and please cancel those warranty,service plan and dot something, my father didn't request them.I THANK YOU AS I WAIT TO HEAR FROM YOU.
