Telkom nightmare. What now?

If I can give no stars I would. I had for many years had a ADSL internet with Telkom. Copper wire were ******e last year and after waiting 2 weeks, with no internet I were told that they are not replacing the copper wire. I then get a email stating that as they not replacing the wire I must go to my nearest Telkom office and get a free wireless router. I did that and pay R999.00 a month for the service. We now have fibre in our neighborhood and decided to go with Vox for fibre. Now trying to cancel my Telkom account is proofing to be very, very difficult. When I eventually got through, I were told I have a contract until next year. I did not want another contract. Why would I want to continue with inefficient service The only reason I went to get the router were because they told me so. This has hugh ramifications financially for me. But Telkom is just not listening to what I'm saying. So what now. Can't speak to anyone of authority.
