Is it Cancelled or Not

I no longer had need of a home phone or ADSL line. On Dec 30th 2015 I went to the Telkom offices in Claremont and paid the account up after obtaining the balance via an SMS service that Telkom provide. The lady at the Claremont Telkom (Stadium on Main) faxed the cancellation to Telkom Cancellations. I have subsequently (10 days ago) received a call from Telkom that they have received my cancellation and have prioritised the cancellation backdating the suspension to 23rd December (when I initially filled in the form) ...... Lo and behold I get an SMS from Telkom advising my \service has been suspended\" and please pay the outstanding amount of *** to ensure reconnection within 48 hours ...... well according to me there is no outstanding amount and if I cancelled the service why would I want reconnection ?????"
