UTI — childrens gift growth fund-1986

I had purchased CGGF-1986 on 18/10/1997 and the same matured on 09/08/2018. There was no information from UTI regarding the status. However taking lot of troublr I was able to obtain a form for redemption of the amount due. Since I was made to approach the UTI office many times without any clarity regarding the formalities to be followed, I was able to complete the filling of the form with account details of my daughter Ms.Surabhi.R.Jaathe in Sepember 2019 and submitted the request to the UTI office situated in Halasur, Bengaluru. Unfortunately I havenot heard anything so far. The Bengaluru office staff say only H.O.has to answer. Please help me The policy no is [protected] DOP 18/10/1997, DOM 09/08/2018. Than You J.N.RAVI
