Telkom can not cancel a ADSL line

So I cancelled my ADSL line for the first time in July 2015. No one responded to this cancellation and I did not recieve any feed back that I send the details to the wrong department so I send al the forms and documantation again in Dec. But I am still being billed for Feb. I know there is a 30 day notice period. I have contacted theri social media team and the only response I get from them is We will follow up with the Cancellations team, The first response I recieved from them regarding this issue was one 19/12/2015 the last same exact response I recieved was on 25/01/2016 stating \Please accept our sincerest apology for the dealy, we will follow up with the cancellations team and provide you with feedback. Thank you. ^KS\" <br> <br> Since then they have not responded to one of my direct messages to them. I have all the documenttaion and email so they have no excuse<br> <br> AS the national telecommunicatiobs provider for one of the biggest economies in Africa I find this unacceptable and disgraceful.<br> <br> Needless to say I will never deal with Telkom again and will look elsewhere for an ISP!!"
