Cancelled Telkom Services in Dec 2017, still getting billed!!

I called Telkom in Oct of 2017 to cancel my ADSL service and phone line.

I got a call in December to say they received my request, and said it was now set to cancel.

I called the call centre in Jan 2018 to confirm that all is cancelled, even after my line and services no longer work at home and getting debited for the services i don't have.

They said that something still had to be done and that they would resolve after 30 min call with them and the accounts department.

Today, 01 Feb 2018 again i get another debit order, for a service i no longer even have for the past 2 months.

This is UNACCEPTABLE !!!! Where is my refund and where is the so called customer service?

Pathetic!!!
