Charging for already canceled services!!!

<p>My Telkom internet and phone service has been canceled, and has been off since 30 May 2016. I have now received an Invoice from Telkom for 9 June 2016 to 8 July 2016. I phoned them to explain my service has already been canceled and off, so I do not understand how I am charged for that time and I will not be paying for that time. I have recieved a reference number last week (14 June 2016 - ********** 3) and they told me in 2 days I will be contacted, I am still waiting for this to happen. I think this is absolutely unacceptable, and I really hope someone will be able to assist me with this problem.</p>
