Bad customer service

Very poor service. Discovery vitality apparently claims they delivered my healthyfood card twice via post and once via courier and none of them got delivered. The last attempt through their courier company, that also didn't get delivered. I asked for details of which courier company was used and who delivered it on which day and who signed for the parcel--- I did not get any response. Then I asked to resend and now no one is responding to my emails. Very inefficient staff along with the courier company that is incapable of delivering.
