Consumer Redressal

I bought a micromax handset from snapdeal in October. I switched on the phone after some days. I realised that the piece was defective. I submitted my phone to the micromax service centre in November. They gave me the phone back in January with the assurance that the handset would function properly henceforth. After using the handset for 2 to 3 days I realised that the phone was still very much defective. I had to resubmit my phone to the micromax service centre in January itself. Till date I haven't received my phone back. I have also registered a complaint regarding the same with micromax. The complaint no. is MMX1903154476. I have also sent them numerous emails regarding the same. I haven't received any proper response from them. They keep giving me false assurances. I haven't been able to make fill use of my purchase properly till date. I would be highly obliged if you could look into the problem and grant me relief for the damages I have suffered.
