Hello,I bought a key from Gamivo (I've bought some keys before and had no problems), but it's already been used.
I tried contacting their support, and they asked me to provide a screenshot of chat with steam support to prove that the key was not used by me.
Then
I contacted steam support and wanted them to tell me the key's usage time, but they couldn't tell me due to user privacy.
So
What can I do to prove that this key is not use by me?Does anyone here have similar experience?
