VC accounts from Shenzhen, Fujian have been destroying my listings, it seems they have gotten new techniques to control my listings and accounts.

1. they changed my title

2. they changed "inch" to "IN"

3. they marked my products as “”“pesticide” or“”“sextual products”

4. they left me bad reviews

5. they created A-to-Z

6. malicious follow-up my brand in other counties though i registered my brand in 10 counties

7. more

but now, it seems they have new techniques to control my account. I hardly make any sales recently.

who can help me? Transparency does not have any help at all.
