ICICI Prudential Life Insurance Company — INCORRECT DEDUCTION O[censored]NITS

I have invested in ULIP of ICICI PRUDENTIAL LIFE INSURANCE. My fund was invested in multiplier/flexigrowth plan of the fund.I switched to protector fund after few days.A few days later, I decided to switch back to multipier fund online, but my unit statement online was showing that my previous switch to protector fund had been reverted/invalid & my fund was still shown invested in multiplier /flexigrowth fund.After a gain of around Rs 5000, I switched to protector fund.Around 20 days later, approx. 5000 Rs have been deducted in the name of excess unit allocation. THE FAULT IS AT COMPANY'S END .I have invested in a ULIP where NAVs are daily changing & investor is taking his switching decision based on fund value/unit statement shown on website of company.As such, company's action of deducting Rs 5000 approx after around 2 months for their own fault is not fair.KINDLY ADVISE WHICH AGENCY SHOULD I APPROACH AS COMPANY OFFICIALS ARE NOT WILLING TO RESOLVE MY GRIEVANCE.
