Landline cancellation

#Black Friday. Telkom cancellations service A waste of time. I canceled my Telkom landline on the 25th January 2019 @9.50am. I was given a Ref. number. But continued to bill me. I made a second cancellation on the 9th April 2019 @11.50am given another Ref. Number. They still billed me. After six months I received a bill with a zero balance. **************** letting a customer pay for services not used. This is the 2nd time I had this problem with Telkom. Don’t do cancellations and continue to bill for months only bad service.
