cancellations off 2 contracts at Telkom Mobile

I struggle to cancelled 2 off my Telkom mobile nrs *** & *** from last year. I send mails to [Email Removed] but received no feedback. I phone every week to find out how far is the cancellations but you received every week differend storys at the people by the call centres. There was a case logged wrongly ***5 by the call centres. On 2016-02-18 Sandile Ndaba supervisor off a call centre logged case ***2 and still the nrs are active. Yesterday someone call me to upgrade 2 off my nrs then I tell him my story and I dont want to upgrade he must check if the nrs are cancelled he told me only 1 nr are cancelled. I phone agsin today the call centres and they cant see any case and the 2 nrs are still active. So how long will it Telkom Mobile the cancellation department take to cancelled 2 contracts. I send a few different mails to cancellations. Please who can help with this problem to cancelled this nrs and I also want to migrate 2 of my other contract nrs to pre paid, so I wonder if it will also take 6 months. I was also at Potch direct with the same problem and the petson only tell me there are a dispute logged I must wait for some one to call me.
