Actually we do not got any order and do not do any kind of business during the last month except the 1 million usd order from al ghurair trust(of course it's not real cause i found their company on many scam report websites)
So now the website of my company is on the scam list, what can I do? If there is nothing I can do, then maybe I should just give up my website.

thats just the way it goes. make a phone sales department that can entrance/hustle people so they don't think to google the brand

Seems there is no good solution in this, i learned a lesson, don't ever try to fight with scammers, or just do it silently. Thanks anyway.

that guys email to you makes my brain hurt

defamation me sue cuz u is my brand screwed up....... WHAT!!!!!!!!

Could you explain more about this? Really need more solution in this
