Cellphone Contract

I am faced with another problem from Vodacom concerning a number which is linked to the contract on *** which I requested to be cancelled in which Vodacom cancelled the contract with Immediate effect. However I noticed that the number that is connected to *** which is *** is still active and I keep receving airtime. Can Vodacom explain why this is the case as the *** number was supposed to be cancelled along with the initial *** number. Can Vodacom urgently see to it that the linked number is cancelled since the initial contract I took with Vodacom allowed two phones under one contract of which the other number is ***. Furthermore Vodacom needs to close everything connected to cancelled *** number because that is what should have happened and also what I want and requested. I don't understand why you haven't done so when I requested to have the contract cancelled. I don't want anything remaining or connected to the the said contract. Please find this in order.
