Cancelled card without notification before delivering new card

<p>Last week I requested a new card due to a name change. Today while phoning discovery card to notify them that I will be out of the country from Sunday, I am told that my card is no longer active as I will soon receive the new one. My card has therefore been cancelled without notification or my approval.</p> <p>Firstly, my card should never have been cancelled before I receive the new one. In fact the old card should not have been cancelled until I activate the new one and approve for the old one to be cancelled.</p> <p>This has caused extreme inconvenience since I cannot spend on my card and cannot recieve a payment which I was expecting for travel expenses. Discovery Card's handling of this incident is unacceptable and I would like to know how they will correct this matter.</p>
