I paid 80$ for buying Heroes of the Storm Boost and they even didn't confirm the payment and then cancel my order without refund my money. Their live chat and email support are never work, you maybe wait for 1 year before have reply. This website suck a scam.
p/s : After 1 month, PayPal supporter refunded 80$ to my credit card, but I lost more than 10$ because of money transfer. Say goodbye to this scam website.
