GTC scams in the name of Shanghai Lang Chao Cloud Computing Service Co., Ltd. A fraud named Xinyi Li

I’ve checked my card number many times. But when I withdrew funds, the customer service said my card number was wrong and asked me to unfreeze my account. The guy named Xinyi Li who recommended this broker to me asked me to borrow money and she would also lend me some. While after I added the money, she didn’t lend me. Isn’t it a scam?
