Scamming broker KVB/ Not giving the initial deposi

I referred a friend to trade with KVB and encouraged him to start trading as he is an intraday trader. Initially, KVB processed his withdrawals, which made him feel confident and attracted to continue trading. However, after he made his third deposit, the company suddenly blocked my referral account without any proper concern or clear explanation. They stated the reason as “abnormal activity,” but we have shared his complete trading history, and anyone can review it to see that there is no abnormal activity. His trading pattern is normal intraday trading. Additionally, the company is not even returning his initial deposit. This situation seems unfair and looks like a scam by the company.
