Telkom, can't do anything right!

I canceled my land-line and adsl line with telkom in April, it's now 8 months later and I am still getting sent invoices that are piling up and worsening my credit score. After numerous calls to their call center, consultant after consultant, team leaders and empty guarantees, I am still waiting for my deposit and confirmation that my account is now done! The consultants can see my account is closed but they can't pay me back? Now I write to you hoping this will get their attention and that they can finally reimburse me or end up losing potential customers. I'm not recommending telkom to anyone. You want internet? Use another provider. The service is horrible, and once you sign up you are stuck until they decide its done. I hope this helps any one who is looking for internet options.
