Pancard Club Ltd. — Payment not received on maturity

My mother was depositing RD with this co. thru an agent. On Sept 10, the RD got matured. On submission of RD receipt, she got cheque of 72000/- from the co. But this chq was bounced twice. Now the co. has told that they will make payment thru NEFT for which they will need the bounce chq. back. They promised payment by Oct 19, but not yet received.
