Well, contrary to many of the complaints of buyers getting scammed after receiving duplicate keys, I had a different experience. To begin, practically my entire library of games (30+ games) were purchased from Eneba, and this is the first duplicate key I have received, which had been from one of their sellers. The problem was mitigated quickly. First, I obtained the duplicate’s activation date by asking Steam support for it (they replied in less than 4 hours). Secondly, I took a few screenshots of my game library and the duplicate key activation error. After sending the above to Eneba, as I opened a support ticket, they inquired to the seller and presented the proof of the error I provided. The seller then promptly replaced the duplicate key with a legitimate key. Eneba is not a scam, and prior to this, all 25-30 purchases went perfectly without an issue. I highly recommend them, would recommend them to friends, as well as use them again.
