Machine does not work. Fully just scrap metal and Alibaba trade assurance order does not work! Alibaba closed dispute for $2900 without providing any evidence button and dispute options. Just closed open disput! For other disput Alibab agreed provide refund for testing materials and give me 3 hours to give them answer. I don't sit at the computer all the time! They give time to agree to a refund until September 15. And we have a 1 day difference. And they close it themselves in 3 hours on September 14th according to our time. When it's nighttime for us and we are sleeping. I consider this some kind of fraud on the part of Alibaba. I didn't expect this from such a platform. Quality:
