Diner's card dont know how to service a client

I have emailed a few times advising my card has expired therefore I can not use this card. they advised that some one would deliver it face to face to me of which nothing has happen over a month ago, I spoke to people on the phone to get feedback however I still do not have a card. I am not disputing last months monthly fee due to Diners as I advised that I need a new card I have emails as proof. when am I getting my renewal card?
