Telkom disregarding cancellation

Dear Telkom I am absolutely disgusted with your service. After months struggling with signal for our LTE router and numerous calls to get a tech out to assist, we decided to cancel our Telkom LTE contract. I made the cancellation online, as I was advised, sent in all the documents to finalize the cancellation. I was told I will be contacted to confirm the cancellation. Weeks have past and the monthly amount was yet again deducted and still I have not received any confirmation or any correspondence. Today I have been on the phone for 3 hours now, have been referred to 9 different numbers and still I have not been assisted in any way. While I was looking for an email address to launch a complaint, I came across hundreds of complaints regarding Telkom, disregarding cancellations and still keep on billing the clients. This is a disgrace and I will make sure that everybody knows the poor poor poor service you offer. Actually, there is not even any service offered.
