1. Make sure you check the balance when your cards are delivered. There may be lesser amount, no amount or even invalid card.
2. Only buy when you are planning to use within 100 days of the purchase otherwise they won't even entertain your request. I have been a long time consumer and I was super disappointed obviously as i lost $150 just because i missed the 100 day window. Both the cards had the balance i checked when purchased but after the 100th day its gone and they dont even bother to check what's the issue. Pathetic as it sounds.
