Fake reviews!!!!

We have recently received a large number of 1-star reviews.

After careful research and analysis, we can confirm that these buyers' reviews are completely fake!

So we wrote an email to complain to the audit team.

But so far we have not received any response from the audit team?

I can't understand why Amazon allows these fake buyer accounts to exist?

Why didn't I get any response to my complaint?

How does Amazon protect the rights of sellers?
