Cards Delivery

I App**** to multiply in 27 Nov 17 I have not received my card to say that I am a member of multiply. So when I phone this morning to cancel the card they tell me that they will post new cards which is fine but I wanted to cancel due to the fact that they say that the cards will be delivered to you within 14 day. Now I have paid for two months and have not benefitted from this at all. So I asked for my money back as I have not been rewarded as yet. Then they tell me that they don't pay money back because they sent the card to me.
