Nedbank is overcharging me on interest

I took a loan with Nedbank a year ago, their interest is the worst m being charged 100% its actual more than what l took from them ,they also have a benefit that says u can review the interest its a green lie l have been to the bank no help ,considering that m upto date with my payments not even one day l missed my instalments l jus feel for those that took out home loans ,please check your Interests 😔💔#daylight*******#Nedbankstopit
