Tds co-op hsg society

My Co-op Housing Society had under taken major repair of the Bdlg in 2012-13 for which we had done TDS given the same thru SBI, we have the challan's.

But did not file return for 2012-13, the company who had done the repair filed the returns by the claim for refund got rejected as my society had not filed the IT Return.

If we (society) file the return now (yr 2014) for 2012-13, can the repair agency claim for the same amount along with the other TDS/IT return this year 2014 and claim refund of the amount? or is the amount lost?

Need your help...
