Telkom Internet and ADSL cancellation nightmare!

I emailed the appropriate forms to cancel my Telkom Internet and ADSL to the email address provided on 26/03/2018. I then phoned to find out the progress on 05/06/2018 only to be told by Nande that it was still active. I re-emailed the forms to the email address that she provided me with that same day and still my internet has not been cancelled! I have had no internet access since February this year and would like to know how long it takes to cancel an internet contract with Telkom? I am a pensioner on a limited budget and cannot continue to pay for a service that I do not have!
