New Discovery Bank card being declined for international purchases

I am an all-in Discovery user. I have almost all their products and enjoy the company.

I was migrated over from the Card division to the new Bank, and am okay with this (though I miss the link to FNB). BUT, my new card is unable to make international payments. All my e-book and audible purchases are being declined.

I called the bank and was told they were flagged as ***** - clearly because they think I am outside the country. And yet I've been making the same purchases with my Discovery Card for years! I was transferred to the ***** department, which didn't pick up the phone. I hung up after 12 minutes.

Discovery, PLEASE fix this before I lose all the purchases I've tried to make (e-content prices fluctuate and I buy when they're on special).

Please call me and fix this ASAP!
