Incorrect Balance - ******* dealings!

I received a call for the Maintenance contract of R20 which the lady stated that if I do not want it I can request cancellation within 30days and I won't be charged to cancel or to pay the activation fee. I requested this cancellation within 3 days of receiving the call and have sent numerous emails to you. While this is now cancelled after tons of emails sent the maintenance contract amounts with activation fee still shows on my balance. As I have repeatedly stated on my emails, the only contract fee I've been paying and will continue paying is for the R319 Compact Package therefore I kindly ask for the millionth times that you please update my balance as the Sales Agent clearly advised I won't be charged if Maintenance was cancelled. I don't know if this is a tech-tic to lure customers to get extra cash from them but this goes against NCA. Please update my balance correctly to only display R319. Thank you.
