I purchased my Micromax A116 on 26.05.2013 vide bill No.1646 at surya communications. IMEI No.91130 4252 473016 woth of Rs.13,850/-

I got my mobile glass and battery changed on 24.04.2014 at Harihar communications, Ameerpet, Hyderabad, apart no issues with my mobile, Within a hour my power button was not working. soon i approached them, they are complaining that there is water injected in the battery and motherbood is failed.

How a newly purchased battery got down with in hour? How a motherbood got failed?How my perfectly working mobile got dead? Sure there is a mishandling of my mobile while reparing powerb utton..

My mobile is still in waranty..

I request to solve the issue within a week as no where my fault is there in handling my mobile.

Chaitanya
