I had earned a visa rewards card from a credit card I have. The rewards card was issued for {$50.00}. When I called to activate the card, they advised that the cards value was now {$47.00}. I tried to used the card at a restaurant and it was denied. I contacted the credit card who issued the visa rewards card and they had no clue as to why it was denied. I then was shopping and decided to try using the card again. The first time it was swiped, it came back declined. The salesperson tried swiping again and it indicated that I had {$42.00} on the card. We did go ahead and use the card. For a {$50.00} reward I was 'shorted ' {$7.00}. ( I was going contact visa regarding the first denial, however, when I called the number, I was advised there would be a fee for talking to them - needless to say, I immediately hung up rather than further decrease the card value.
