********** debit order

I would like to complain about Cell C service ,they are taking money for a contract that I cancelled in January ,they are consultants are ***** ,I have been to and from the Westgate and Newtown branch ,where I have been told on numerous occasions that my contract is indeed cancelled ,I have two contracts with them ,of which the first one ended in August 2017,to my surprise this year when I cancelled the second one which was due for an upgrade in January ,I called and cancelled it (the contract has 3 headsets billed under one contract number ********** 35)then on the 23/03/2018 I went to the Westgate branch and they advised me that only one number of the three was cancelled my question to Cell C is I only took out one contract ,but now why do I have to cancel three contracts ,and I am definitely going to kae this up with the Ombuds as I believe that this is ******* .
