Is Cointiger a scam, or is it legit?

First of all I checked the MT5 platform after one of my dealer was out of contact. When I opened the MT5 unfortunately it says invalid account though all the login info was correct. After that immediately, I checked the cointiger website but it shows the website is not accessible. More I tried to reach the support team also but no response from support team as well. I was led to join this broker by one of the Chinese lady living in US but I think she never revealed her true identity to me. But she promised to get me a lot of profit and told me to get my other friends also join this broker promising to get me profit for free after dealing. Thankfully none of my friend joined this platform. In the end i was the only victim and I lost 6K in total as I was planning to withdraw as soon as possible.
