Cipla Pharmaceuticals - Refund of Bond amount for Fake offer

My sister completed her B.Tech Bio Technology, received a call from Naukri (SAURABH SHARMA - **********) stating her profile got selected for MNC - Cipla Pharmaceuticals as Clinical Researcher and need to pay **** as Initial amount to start interview, if not selected thy will refund the amount.
So we paid **** and she completed *-* levels of round done by CIPLA Team, HR Named - Aditiya Rao - **********
Finally got selected but in order to send offer they asked R.***** as security bond as its going to be work from home. So we even paid Rs.***** and received offer letter in the name of CIPLA but next day they again asked ***** for insurance, we got tensed and asked to return all the amount as cancelling the offer.
But till now no refund and all the mobile number is switched off.
I wrote an complaint to CIPLA team that my sister received the offer in there company name and also the amount we paid to the bank account name is CIPLA only, refer the below response from the original CIPLA Team
''Please note that Cipla has already lodged a police complaint in this matter and has reported the fraudulent bank account number intimated by you. The authorities are investigating this matter to identify and take strict legal action against the perpetrators. We urge you to kindly get in touch with the investigating authorities and report this offence as an aggrieved person, and seek appropriate remedies, including getting the amount back from the fraudsters.
Cipla Limited (and/or its group companies) follows a formal recruitment process through its own HR department and does not ask for any security deposit or fees (refundable or non-refundable) at any stage of recruitment process. We were aware about such practices in the industry and therefore we had prominently placed a cautionary public notice with regards to such Recruitment Frauds on our website. URL to the said notice is as follows https://www.cipla.com/caution-notice-recruitment-fraud. We sympathize with you on the entire incident and again advise you to report this offence at the earliest.''
Total amount we paid is ***** and **** = *****
already i didn't receive any salary in this corona time and we are happy for her to get new job, but they cheated as completely

PLEASE TAKE SEVERE ACTION AGAINST THEM AND PLEASE REFUND THE AMOUNT
