Nedbank non Disclosure fleecing clients

I have an issue with Nedbank relating to non disclosure. There is a package available on my online portfolio that is an accounting application. I assumed that this was a free service for Nedbank online internet clients. I clicked on it to activate it but never used it as I was just curious to se what it was all about. However to my dismay I get billed R188 for this package. At no point did Nedbank ever indicate that this was a paid service. I immediately cancelled it .Had I know or was informed by Nedbank upfront that it was a paid service I would not have activated it.This is **************** Nedbank you are fleecing your loyal customers and duping them into paying extra. I requested a refund a month ago but have had no response from Nedbank .What poor service to add insult to injury. I believe that from an ethical standpoint Nedbank needs to refund this amount firstly because they never disclosed that it was a paid service and secondly I never used it at all
