Whom to contact when Liquid ETF dividend is not received?

I have bought KOTAKLIQ liquid ETF 35 days back and I have not recieved any divident payout shares until now (also no fraction units received, I have checked in Breakdown). How can I resolve the issue?

Did you also login inside the CDSL/NSDL depository and check?

Yes, I have checked in CDSL easi. The Quanity is same as I intially bought.
