Pacl India — clarification on claim process for refund on sebipaclrefund.co.in

I have many queries on claim process offered by m/s lodha committee in reference to refunds to be given by pacl. But we are not provided with any way to communicate with either pacl or sebi or lodha committee except one helpline no mentioned on www.sebipaclrefund.co.in [protected]. But this no doesn't connect any time, although this no ringed two times but no body responded. My concerns are as below mentioned:
1. Please resolve above mentioned issue at first.
2. While claiming online for refund in step-1 claim amount is asked and that amount according to demonstration video should be total principal amount investors have invested. Does it mean that investors will get only principal amount in return. And if interest is returned will it be calculated by lodha committee itself.
3. Few days or months before pacl was taken over by sebi, original documents (Policy certificate, installment receipts) were submitted of few investors as their policy got mature exactly at that time, so they don't have their documents with them now. What is the procedure to get refund for such investors.
4. Many investors have lost few or more receipts. How will they get whole money they have invested.
