Number cancelled without prior contact

I sent an e-mail to [Email Removed] on 7 January 2016 as my contract was drawing towards it's expiry date. On the form that I needed to fill out and forward I specifically stated that the number was to be migrated to a pre-paid service. My number ha now been completely cancelled I am now without service. I then called 180 on 2 occasions and BOTH times my call was cut and no one agent contacted me back but they did have my details already I guess it was expected of me to call back and fall in the queue again. I also sent an e-mail to cancellations to inform them of the error I received no response. I also sent an e-mail to Brenda Thsikudu an ops in the call centre to the same effect I also never received any response and up till this moment I am without service. I am absolutely appalled at the constant poor service being received from Telkom on my contracts.
