Month's of no responses - very poor service

<p>I received an account during November 2016 from Telkom for my telephone and internet service just after I changed my contract and an amount of R604 was added for a list of TBIS usage. I phoned them and sent emails on numerous occasions and every time I am told that the enquiry will be referred to the relevant section to respond to me since they have to explain why they 'rejected' my query. I have proof on my daily adsl feedback email that I still had data left at the end of the month. To date still no response and the amount was deducted on a monthly basis with penalty/interest added. </p>
