Always getting it wrong!

I upgraded my gold cheque account to platinum cheque account. after 5 days I received my new card which was delivered to me. I read the letter and it gave me all these WONDERFULL options how to activate my card online and change my pin online!!! as I don't always trust these methods, I decided to go into an FNB branch instead. went in activated my card and changed my pin to my preferred pin. before I left the fnb branch I asked the lady that helped me will my card work now when I go to the shops. she rep**** \YES". we to the shops... declined declined declined... luckily for me I did not destroy my old card yet"
