Valve employee on Skype

[Mando]

So i just had a problem with my phone number. I just wanted it removed from a community banned account of mine. A guy told me to ask for help to a Valve employee called "Solo"
His profile: https://steamcommunity.com/id/anster
He gave me his Skype, i gave the banned profile and then he screen shared me that he has the Valve employee badge. It looked good to me. He asked me to give him a screenshot of my recent purchases on my main account(not the banned one). After that he asked me to change my mail to his. I trusted him and i changed it, then he sent me a screenshot of the account. He told me that he temporary community ban it because he found some errors. My account that he banned: https://steamcommunity.com/id/pulescu
Then he told me that he needs to validate the account and asked me to buy 50$ steam gift card.
I told him that i don't have 50$ and then he said that he will to 30$.
I refused and then he stopped responding.
He also showed me some comments on his profile from his "clients"

But i still don't understand how he got it community banned in 2 minutes.
