Debt recovery - My case is both civil and criminal matters

My case is both civil and criminal matters. My location is Hyderabad and my 74yrs father (senior citizen) is the complainant in both cases filed against a public limited company to recover his unpaid dues. My story so far.. There is a public ltd company by name Sathavahana Ispat Ltd (BSE and NSE registered). My father supplied few products in 2015, his compnay is SSI not even MSME.. and SIL did not pay his dues since 2015.. the due amount was Rs24Lakhs. We have all the purchase orders and delivery challans accepted by SIL, including CST VAT challans for which my father already paid taxes even though money did not come from SIL. In 2017 we filed FIR against SIL u/s 420, 406IPC.. immediately SIL went to TS High Court and got a interim stay order on my FIR while the original order is kept pending @ HC..since 2017 my case did not move an inch in High Court. My father also filed posting slip in HC in March 2020 and even that is showing "pending for scrutiny". Although I met 6 IPS officers nobody helped to move my case to the HC judge bench.. Next in 2018 we also filed Civil suite in City Civil court and case also dragging there. Now last month in August 2021..SIL was accepted as insolvent company by NCLT and they filed stay petition in Civil court bcos SIL is now under insolvency. This company is NPA with 4 nationalised banks and did not repay Rs1381+ crores. 8 companies also went to NCLT and SIL setteled matters with 3 companies and 5 companies are struck in my same situation bcos of the new NCLT order. My question is (a) How do i push my case to the HC bench and ask Court to vacate stay order and in a time bound manner tell the police to file chargesheet and also instruct the lower court to finish trial within 1 year (bcos my father is a senior citizen).. or (2) few lawyer suggested i file PIL in HC by converting my existing CRLP case itself - so is this possible? My father is party-in-person in HC while we have a lawyer representing us in Civil court...pls help with free advices. I dont want to hire a lawyer in HC bcos I cannot pay another 2 or 3 Lacs just pursuing cases without money flowing into my account.. Appreciate all the help from the ppl in this network. Thank you.
