VIP club added when I said not interested

Yesterday (23.02.16) I got a call from a call centre agent who, after giving me the benefits of being a VIP club member, asked me if I was interested in joining. I said very clearly that I was not interested. Today (24.02.16) I get a call from another call centre agent saying that I can collect my new VIP card at my nearest Edgars store. After telling him I said I was interested he said I need to go in to a store to cancel my card. I said I will not since I said I was not interested he said he does't know anything about the call only that I need to go in store to cancel the card if I want. This is absolute nonsense. I WILL NOT go in to a store to cancel something I very clearly said I was not interested in. Cancel the card and call me to confirm that it is cancelled.
