I purchased 4 Uber gift cards from EJ Gift Card, 2 of them have been used by others. I opened the claims and also send the email to them, they replied that email on the same day invested the issue and sent the replacement after two business days. I'm happy with this site even though the payment method is a bit tricky.
Tip for consumers: Send the email to their support email address, they respond quickly.
Thank you so much for such a great review! This made our day.
