Still no new membership card

I got married and had to change my details. I've been waiting since April for my new card, and when I enquired about it a month or so back I was told that the lady handling my info was no longer working there, as well as I had to send all my new information again, which means my information was never changed. Every time I ask about it all I get is, \its on its way"or \""its the post office\"""
