I purchased an Office 365 key. Turns out, it came already activated on a different Windows account. I contacted support, and they informed me that they would not refund me unless I listed the key again for sale and waited for someone else to buy it. It’s a pyramid scheme, you get scammed, and only get your money back from scamming other people.My luck was that Paypal interveened and refunded me, otherwise they would’ve still have my money.
