Incompetence,laziness or God know what.

So i phoned in & cancelled my adsl due to telkom not having fibre Infrastructure in my area,was then told to only do it online,of which i have done it 4 times now & counting since April 2018,i call in with the ref #s & im told someone will call and sort it and to no surprise no one does,its now 5 months trying to cancel a service that i no longer use,please if there is someone there @ Telkom who is dedicated to their jobs assist me in cancelling my adsl + showmax & retain my number.
