I purchased my mi 4i cell phone just 2 months back . I submitted my cell phone to service center on march 12, 2016 as home button is not functioning properly . But unnecessarily they postponing the days . Still i didnt get my cell back . Even i registered compliant regarding this with the customer care but its of no use . Can any one help me in this .

If they are unable to resolve the problem, i am expecting new mobile [since it is purchased just 2 months back] .
Anyone please help me with this .
