Company want salary back of three months as they said I left the job in January and was relieved in March

After relieving me on 31 march company want salary back of three months as they said I left the job in January. Can the company take any action to take a salary back after relieving? They paid till March 31 to me, I have salary slips and relieving letters. Can the recover back salary in any case as I go to office or not.

Dear Pratap,
As per your statement, If the company has issued you a relieving letter, then they should not be asking you the salary for the period which you have not served. Post issuance of exit documents, companies deduct any dues which is pending from the employee's side is always deducted from the employee's full and final settlement.
Has the company paid you your full and final settlement? If not then the company has full rights to ask you for payment of 3 months salary. If they have paid you, then you need to talk to them and settle a amount with them or pay them the entire amount as desired.
