I have been having non stop problems ever since i started using Samsung Rewards. First the "cash back" Rewards are not Cash. They are redeemed using a digital Samsung Rewards Debit Mastercard, this card is not physical, it has no card information for use online. No Card # or CVC. Second, there are no instructions on how to use this card 😑. I had to contact support to find out how to use it. Just after I made a few purchases my card/account was disabled and support can't/won't help. Terrible.
