Cancelled Phone Contract but still paying for it

<p>I took out a phone with FNB a month ago.</p> <p>However since it was locked the phone was returned and sent back to FNB, first it was returned to the branch where I got it from, however they didn't take it but sent a courier a week later to fetch it.</p> <p> </p> <p>I confirmed the whole contract has been cancelled.</p> <p> </p> <p>However FNB took the monthly subscription from my account today.</p> <p>I don't have anything but I have to pay for it.</p> <p> </p> <p>So much trouble just to return a phone within the 7 day period.</p>
