Does Vodacom Understand What Cancellation Means.

Due to shoddy service we finally cancelled our contract. On the 27July 2016, paid Balance of Contract fees - Ken R17265.09. Pat R2072.47. Total R19337.56. Emailed copy of payment, plus ID plus signed Premature Contract forms to Retentions Saves department. Ref EC-0447-32LZ6C. Made calls confirming forms had been received same day. On the 31July, Boitumelo confirmed cancelled, Nasiphi and Pashnirka at +-8.45 on the 02Aug also confirmed cancelled. Due to keeping old numbers, we had to switch cells off on the 30th Aug and switch back on the 31Aug. Vodacom in November 2017 deducted a Debit order which we reversed. Finally 13 Dec 2017managed to speak to Khanyisile who put me through to Anele who then informed me Vodacom creates Ghost Numbers. We need to cancel contract. Please EXPLAIN TO ME WHAT DID WE PAY OVER R19337.56 PLUS GIVE RELEVANT DOCUMENTATION TO IF CONTRACT WAS NOT CANCELLED.
