Can anyone suggest how to deal with this scam company Bitmain?

3 antminers we bought from them came dead on arrival, shipped 4 times for repair for the same machine, none came back good. Wasting my money and time on shipment.
Now one of machine they said shipped me 1 month ago, until now, it is not shipped:

They keep telling they are checking or saying it is shipped.
Even I called Fedex they told me cleared not shipped to them yet, Bitmain was lying.

Send at least 200 emails to support with useless repsonse, day by day now after 3 months not sending us back the machine.

We wished we never buy any bitmain antminer but other brand.
If you guys are buying, please do not buy it.

I will post a youtube video and even publish all my stories to newspaper soon.
