unfairly billing

I am sick and tired of telkom s department 8@ta. I cancelled my account and still the debit orders go off. After various attempts and complaints it still go of. I am over extremely angry. This is completely pathetic! Been seven months now! What is going on!!!! I want someone if telkom who has the ability to refund me and cancel the account. I am frustrated . I work with almost seven hundred people a day. This is not good marketing for telkom.
