Constant struggle with Telkom

I am tired of struggling with Telkom. Finally after 6 months the line was finally cancelled but we now still receive statements of just over R900 due which is not possible. All invoices after September 2017 must be cancelled as this was the original cancelled date but Telkom only succeeded in canceling after 6 months. I have tried chatting to a consultant online but after going through everything se told me they were offline and she cant help me further. Telkom this is unacceptable. How many reviews do you want me to write on your company. Please sort this out ASAP!!!!!!!!!
