Telkom at it's worst

Last year April 2018 ,I signed up for the adsl line....by June 2018 nothing was installed however received a bill which was highly strange as no installations took place.....called telkom numerous times since July 2018 to cancel the subscription/application to date nothing had been cancelled they might be the cheapest service providers ,however the worst problem solving company....after receiving another bill in December ,I again called to have all everything cancelled , still nothing has been done as another bill was received yesterday.
