Telkom service- Very Disappointing

I wanted to cancel my Telkom line and went to the Claremont office of Telkom. When I got there a consultant said he cannot assist me even though there was no other customers in the branch they told me I can only cancel my land line by doing it on line and gave me the web address and I had to leave. I went on line and done the application twice as I got a sms to say the first one was not successful however yesterday I got an sms from Telkom telling me I owe them R395 instead of R164 so this tells me the contract was not cancelled. I went to the N1 City branch today and they confirmed the line has not been cancelled. I provided the Consultant with the proof of my contract I cancelled with the ref number via e mail and asked them to cc me in the mail they escalating for me, they said No this is not allowed. I asked them how long I must wait for feedback before I come back to them and their response to me was, they don’t know. I had the worst customer service from Telkom and highly disappointed that I visited their branch twice and done 2 online applications to cancel my land line and still not a happy client with no resolution as yet.
