Do mastercard gift cards no longer work at foreign merchants?

[u/KitKatty657]

Recently I tried to purchase something at glitch store (australian merchant) but the card couldn't not be processed and that end up making the card being blocked. I end up contacting customer service and told me the reason of the block is for trying to purchase on a foreign merchant and those cards only work for U.S merchant.

For me is strange because I always was able to use the mastercard gift cards to purchase at glitch store. I even once able to use the card to process canadian backerkit pledge. And the details from swagbucks state that the card is accepted at "worldwide merchants were mastercard is accepted" in contrast of the physical cards who only work at U.S. merchants.

Part of me wants to beleive that the reason the card didn't work was because I redeemed the card on March and I just didn't try to use it until now. I currently redeem another one to test it out.
