Paid for a game using Difmark and waited the allotted time, nothing came. Contacted the seller directly even though the green light showed they were online and active. Got a reply 2 hours later stating the game code they have isn't physically in stock and I can choose another game from they physical stock. They showed 3 in stock for the game I chose. I requested a refund but seller didn't bother so I requested a refund expecting to go back to my credit card. Nope it is locked to use on Difmarks' site. Scam to say the least and I lost credit due to they charge a transaction fee so I lost 1.70ish on a transaction which didn't go through due to being out of stock. Will not use again, I will stick to Allkeys etc
