ICICI Prudential AMC — fraud on redeem process

Address:

22 mill didwana teh. lalsot dist. dausa, Dausa, Rajasthan, 303511

My icici prudential bluechip fund folio no. Is 14944204/12
I invested 5000 rupees in this fund and proceed redemption at 4 march 2020 but it is no proceed by iprutoch app
Then i proceed switch (That means close)
But it proceed nothing and then i again redeem two time at 5 march
Then again redeem 6 march, 7 march, 8 march, and 9 march
Then the reedem of 9march proceed and the value of nav at that day is very low
But they automatically proceed redemption at 9 march and my amount get 400 rupees less

So this is due to the fraud of this app
I tried redemption process by imobie app and iprutech app but when i call to imobie app customer care then they said about iprutech customer
And i tried it many time but they cut my call all time
