The SAHARA group company you are referring to is a NBFC or Para banking company???? Read the rules applicable to such companies carefully. There are reports that SAHARA is exiting from NBFC business. What is fate of Para banking is not known to us?
If the company is already closed then you may construe that it is making a pass on you and it shall be better to approach a lawyer and police ……..
Do you have the copy of original deposit receipt?
If yes declare the claim of company of refund as fake.
However issue a notice (which you can also issue) even if by email addressed to the BM of local office, office which has issued deposit receipt, MD, Chairman of the company and demand to make payment within next 7 days…
If the company yields to your demand and contacts you on phone ask them to supply you a written communication to this effect.
This time please take care that you obtain the acknowledgment under seal and signature of the competent employee of the company stating that it has received original deposit receipt for payment to you and obtain the payment on the spot.
If the company claims that payment shall be processed and sent later you may not handover the original deposit receipt and pull then to appropriate forum e.g. DCDRF, Court of law…..
Valuable advice of learned experts/members is sought.
