Unable to cancel subcription

This is on behalf from my wife. My wife tried to cancel this amazing vouchers for the last few days as every time she call nobody is available to assist and the rude and have no telephone manners or customer relationship. Finally she get someone to assist and ask the customer service if she cancel this amazing voucher subscription she she was advise that they will cancel this but she needs to pay R500.00 for R99.00 subscription nothing have been used no vouchers have been downloaded. Then she try to speak to the Team Leader Lindsay or Sara or Adeep with no in avail always busy on a call. The I tried to give it ago and to cal Lindnsay while holding on the line I hear that Lindsay was call to the phone and he ask who is it and Pam said a customer and he bluntly tell the customer I busy. I want this subscription to be cancel or I will take legal action as nothing about cancellations fees was mentioned when try to get the customer to sign up for the subscription. yesterday my wife tried again to cancel it again then Lindsay advise that she needs a laptop to logon and then she will see all the vouchers nothing like that no vouchers that we can use as all the vouchers is useless. Lindsay also advise my wife that she needs a Android phone to logon as the apple device is not allowing what she want to see and that a BS because what I saw on the website from my laptop and also on My Apple device is exactly the same info. Please tell why my wife cannot cancel as she was only sign up this week with in 7 days.
