What the devil is going on with Quant Mutual Fund?

They have become the worst performing fund in their category for the last 1 year and have dropped extensively in last 3 year returns. (Check mutual funds sahi hai ) This downfall started after their SEBI raids. Something is seriously wrong. It's not even performing average, but straight up bottom of the chart. Something is seriously wrong. What to do?

Update: I cant post images. But in multi cap, check Quant Active fund. In mutual funds sahi hai website. It's at the rock bottom in 1 yr returns and 3 year it's at bottom excluding the new ones which have not reported 3 yr earnings.

Isn't that a massive red flag? What do you make of this exact scenario?
