I think they are a real scam! I really believe they may steal your research and publish it under other people's names!!! AVOID them certainly>>>
I had the WORST service ever from them, and when I asked for a refund as they promise %100 satisfaction guarantee on their fake website they told me that they will publish my research without my consent as they own my research!!!! Imagine!
after that, they stopped communicating with me and didn't get back to me since then; and I have been trying to get my money back for more than 45 days now with no result! They provide so bad services. They don't have anything real at all! No real office, no facebook, twitter...etc, all the links on their website are fake. Shortly, they are a scam!
