New card not sent to me

I am living in the UK at the moment and my card has expired. I have tried numerous times to contact Discovery to get my new card. First I was told they would contact me when it expired. They didn't, Then I was told the card is in Johannesburg at the courier. I was told to speak to the courier who then told me they have to speak to Discovery. So now i am waiting again with no one taking responsibility for a card that I have been charged for. Discovery agents all say they can't phone me or email me to update me and the courier says the same thing. Is there anyone at Discovery who can contact me and help me?
