You asked how to complain about suppliers.

1. Go to the complaint forum on Alibaba Chinese website (http://info.china.alibaba.com/appeal/add tracelog=aliltts) to download the written complaint letter, attach the required materials (including but not limited to remittance voucher, identity certificate, copy of business license, etc.), and mail it to Alibaba Integrity Forum or fax it to 0571-89815503. After receiving valid written materials, Alibaba will promptly verify and handle them, and coordinate with the party complained against to resolve the issue within a specified time. If the party complained against is unable to resolve the issue within the specified time, Alibaba will deal with it accordingly in accordance with the terms of good faith operation.

2. When sending a complaint letter to Alibaba, members are advised to report the case to the local public security agency in order to resolve the issue as soon as possible through legal channels. Alibaba will fully cooperate with the relevant investigations of the public security agency.

3. If you are unable to provide supporting materials, members can post a complaint on the Alibaba complaint forum or call the Alibaba service hotline. Alibaba will keep a record of the case and handle it comprehensively based on the progress of the case. In addition, you can also file a complaint on the Alibaba Business Forum http://club.china.alibaba.com/forum/threadList/115_.html
