No knowledge of me cancelling contract

In Jan 2014 I was offered a cheaper data bundle over the phone by a Vodacom salesperson. I was happy to accept after confirming it would add to my current contract. I then got an SMS saying a data bundle was being activated on a new number. I immediately called and was told I has not signed up for a data bundle, but a data modem and data contract. <br> <br> On the same call I cancelled and laid a complaint about the salesperson for misleading me. I was asked about the couriered package which I told them I had not received and asked them to cancel. It arrived a few days after my cancellation regardless, and I was told by the courier Vodacom would call to arrange collection after I told him I cancelled the contract and didn't want the device.<br> <br> Today I discovered that the contract was \cancelled not collected"according to the sales company"
