Unsatisfied client

Company deducted money from my account on the 15 Nov without my authorization, I have provided proof that i cancelled my subscription before trial period lapsed. And did not get permission to ask Shaw academy to deduct. FNB did not reverse my money. FNB did not go through my case properly. I just want my money back and have FNB close their account i have found a bank that looks after me and my money. I called the contact centre countless times no help offered i sent same complaint.
