Globalchinese-dangerous site!

I want to alarm all the Chinese learners to stay away from the site globalchinese. here is what happened to me:
I have purchased a self learning course they published in the site a sum of 120$.after paying the money I was supposed to get the courses materials.but instead I got a reply that because they cannot withdraw the money from paypal they suggest me to add 80$ and buy another course in which I had no interest,or have my money back.from then on they disappeared completely.all my messages to them were ignored they theft 120$ from me and intended to theif more.they are a bang of cheaters and be aware don’t have any dealings with them.
