Is Wowdoge a Scam? Doge Crypto Miner

Wowdoge located at www.wowdoge.io has been shut down with thousands of people's DOGECOIN. I purchased 500 and had 6 days left. My balance was more than 50 doge before they shut down but did not want to withdraw because I had 6 days left. Also, their Twitter account has been shut down.
