Unauthorized debit order

I had a contract with Telkom which ended in Nov but to date they still debiting me. You keep messing with my account, I am beyond annoyed because what you doing is *****ing . Just because you have my account number does not give you the right to take MY money . I owe you nothing , it’s shocking how we work hard for such companies to come and ***** our hard earned cash like we work for them

On top of that a consultant called me from Telkom in Nov to sell me a WiFi device they had on special, two months later I can’t trace that consultant and did not receive the device so I am even wondering if my details were not sold for ****s. I am so disappointed in you and would never again do business with you
