Dear Team, This is to inform regarding bad quality manufacturing defect in Mobile x253 in outgoing voice disturbance (some stupid humming sound) . I had purchased my Micromax x253 on 23/06/2014, it started problem in outgoing voice with in a week. when i showed it to service center (M/S. Devanshu cellcom ) they replaced mic. but after one week same problem of humming in outgoing voice call. they again replaced mic. But problem remained same. they replaced mic more than 4 times and update phone software 2 times. but humming sound problem not resolved. So, they submit my phone for a month and replaced my phone with new x253. but hight of stupidity of MICROMAX not ends here, new replaced phone also have same stupid humming sound in outgoing voice call. So, Again service center change mic two times but problem remained same. According to Devanshu Cellcom all handset of x253 has same problem and problem is unresolved. So, i asked Micromax to replace my handset x253 with another model handset. I also ask to compensate the inconvenience caused due to this stupid model. Please take an urgent action to resolve the issue on top priority as issue is already running from last two months and change phone MODEL ASAP. Kindly find the attached documents for your refernce
