Young adult benefit card still missing!

This is now my third complaint. I still have not received my young adult benefit card or the money that Discovery owes me! I was told in response to my complaint last week to wait 48 hours for a response. However, that was a week and a half ago! I feel as though Discovery are deliberately ignoring my complaints and not actually dealing with the problem. Perhaps I should phone other insurance companies and see what premiums they can offer me as I'm sure their service will be better at this stage. It's shocking, so quick to take premiums but so slow to pay back the money! (Pun intended).
