mastercard gift card site on the back of their card is impossible to find---so, mastercard is partly to blame.

dumb and impatient me settled for "manage your gift card---login" at top of yahoo search engine for mastercard gift card. the address: www. consumer card access. com

they'll let you spend half of the money on the card, letting you think, when other half is gone that there's some glitch at the site you spending at, or a computer glitch at mastercard---so you might get a second card and go back to the site to finish your purchase.

so, my mastercard complaint and others complaining about mastercard might involve this fake site.
