Blocked paid for credit card

I pay my acc via debit order when I tried using my credit card it doesn't allow me to do so, after speaking to the call centre I am advised to email my proof of address and id in order for them to activate my card because it is put on hold, I emailed requested documents to the email address just to find out it is the incorrect address, I emailed it to Ladysmith branch with no repsonse whatsoever, I want my card unblock asap, I dont know why it's been put on hold to start with
