Mutual funds - Upcoming scam

Lately, there have been news surfacing about some incidents where discounts brokers like Grow have not even invested a user’s money in mutual funds, and when this guy wanted to redeem, he realized, the fund he has been paying for has not even been invested.

I have a feeling that jext big scam is gonna be a mutual fund scam as tra king on where your money is invested is not possible and these big houses like quant, mirae, etc are showing really good returns ....what if they vanish in thin air someday...

Your thoughts? I'm investing in stocks directly as don't want to take risk with my money.
