Cancellation ADSL line

On 25 Oct I submitted the correct documentation requesting ADSL line to be cancelled. On 10 Nov I received an email with the same blank document, requesting I complete exactly the same document, I re submitted....nothing has been done.....nothing on Telkom systems regarding this....cannot get to speak to correct Dept when I call Telkom....get told to email again and will get reply from same Dept in 10 days time! We are now a month down the line and no response from Telkom at all......have contacted every Dept in Telkom....nobody can help me! Cannot get to speak to any supervisor or manager...this is a disgrace!
