It sometimes happens. You received a defect. Unfortunately we can't prevent them, but we will solve it. Luckily less than 1% of our items are defective, so it rarely happens that we have to provide a refund.If you are one of the unlucky ones please let us know and we will try to make you happy again.
Send us an e-mail at email@example.com and we will get back to you. Let us know when you bought the card, how you used it and if you have pictures of the defect that's even better.
