Vodacom is a day light *******

I have called vodacom in April to cancel my contract for my 2 numbersthat were due, everything was done and confirmation sent for cancelation. During the period of May I received a call to upgrade my accounts as I have 4 numbers I agreed to upgrade for 2 numbers which is 1 that is existing and 1 that I request for cancelation. From there consultant was selfish because she didn't activate my caller identity. I had to cancel the upgrade within 5 days. Now to my surprise I am charged for the numbers that I requested for cancelation and installment is too high. How can someone activate my contract that I cancel before. Who gave a permission for activation. I regret the day I agreed to upgrade my accounts with Vpdacom as I was almost leaving to Telkom. I want those numbers to be canceled as I requested. I always receive a call to upgrade which I am not going to upgrade my numbers, instead I am going to port my number to Telkom. If feel like I'm ****med coz everyone who called for upgrade when I explain my situation they keep on saying different stories as if they just picked from the street and placed to work without knowing what they are talking about.
