FNB is not protecing me

I bought a laptop from Makro. Installed was mcafee. Which i had to buy. A year later, they took just over R2000 from my account. I immediately tried to stop it. This was beginning february. Fnb told me to fill in some forms, and mail it back. I did that. I got the confirmation email. And they said the money will be reversed to my account after 7 working days. If not. I should contact them again. After 7 Days. I did. And nothing was done. They said they will check on it, nothing.at the end of Feb. I phoned again. Some lady just said they did not recive any documentations. I should submit it again. His was after a month. Then they said my case is reviewed at 25 March. They tried ohoning me once in Feb, which i missed cause i was in class. Since today, 1 May, nothing happened, nobody followed up. Nobody told me anything. But FNB was happy to make me pay interrest on the money that was deducted in my overdraft, which i am still struggeling today, to make up for the loss. R2000 may seem like change. It was my rent, which i had to pay on my overdraft. My bank did not protect me. They didnt even bother to help. Why should they. My business as a single person doesnt meen anything for them. As soon as i am debt free, i am closing my accounts with FNB.
