ICICI Prudential AMC — non performing fund - false commitments - folio no 8599759 / 07

I invested since sep 2016 till date rs 5000/- per month as sip in this scheme from icici prudential - value discovery growth fund. The fund has been showing very good performance and returns upto 15-18% in the past. However, i have been watching the returns and it has been very low from the investment. The amount invested and after returns, the current value is showing hardly 1-2% return in the span of 4 years. Why is this cheating behavior? I have invested in other similar funds in the past with the other companies and have always got a fair return. The market was a little downside during start of corona, but otherwise it has been performing well. Then why so low returns? Normal bank deposit would have given me a better return on savings. Where is amount invested going? Who is eating up? Please provide a fair response, the trust is lost hence please provide a justified response in favor of customers.
