Sir i submitted my mobile model A87 for repair within guarantee period by JOBSHEET NO E060068-0713-4441532 on 6/7/13 at authorized Micromax SERVICE centre. After long time they reply me that my mobile is in guaranty period and problem not repair so they swap my model 3G ENABLE SET WITH 2G ENABLE MODEL A62. BUT IT NOT GOOD WHY THEY CHANGE MY 3G ENABLE SET WITH 2G SET. I TAKE A87 FOR ONLY 3G USES. WHEN I REFUSE TO RECEIVE THEY REPLY THAT MY MOBILE SWAP BY MICROMAX & NOW THEY NOT DO ANYTHING FOR ME. MY MOBILE NO 9431524886.
