Micromax — Non return of my tablet

On 28th march 2016, i went to mircomax service centre in Civilines branch, Allahabad and gave my mircomax canvas P480 tablet for repair as it had issues with charging. Since the product was under warranty i wasnt charged but i was asked to wait for 45 days as the product will take some time to repair. The so called 45 days are already over now and i tried keeping up with them for details but they keep giving excuses, the most common excuse being "the tab will take more 21 days to repair". The warranty date also got over on 19th may 2016 and i really doubt if they'll ever return my tablet. I want my tablet back safe and sound.

P.S. Below is the receipt showing when i gave my tab.
