ADSL LINE CANCELLATION

Hi I had a telkom adsl line for few months and I changed WiFi service provider and I went the branch where I opened the line to ask them to cancel it and I was told that they don't use forms anymore I must log a call on line which I did on the 23rd of April and got reference number ********** 2 till this day this line hasn't been cancelled and every month there's charges of R200 which was my monthly rental I called several times after that was told that someone is appointed on this call but they are not allowed to mention names and was told that they will escalate the issue nothing has been done still. Please Hello Peter I want to help to resolve this issue and this line to be cancelled with no charges on it since I logged a call 3 months ago.

Thank you, SJ Mbele
