Consumer Redressal

I had brought a motorolla phono moto x from flipkart on the 28th of january 2015 ordered in the name of my wife Trecy dias ( order no OD 101927913264888100). The phone started giving me problems in the first week of april .( the earpiece was not working and i could only hear on the speaker). so i sent it to the panaji goa motorolla service centre( c com telecommunications ). They changed the sim card and it started working properly so they sent it back. 'It again gave problems soon after so i sent it back on the 14th of april.2015. they told me this time that the earpiece has gone and that the phone will be repaire in a few days time. i called after 4 days and this time they told me that the phone will be replaced so i was happy with the service promised because the phone was not even three months old and i dont like problems with my devices specially when they are expensive. After that i kept calling to find out the process but nothing is happening .
