How about Beijing Liang Jian Xia Tian Information Technology Co., Ltd.

This company has no credibility. Not cooperating. Promise your line or service before giving money. When you give money, you will find it completely different. Then don't return to wechat, don't answer the phone, and don't refund. It's just dragging you down. Some people suggest that Baidu cheat Beijing Liangjian Technology, and there will be many complaints and experiences of deceived consumers.
