I am using this micromax e313 for the past 3.5 years. I was a happy costumer. 3 months back my sim card was not being detecting. I approached nearby (Thrissur, kerala) authorized service centre. They said it is due to software issues and they changed the software. After receiving it back i noticed that my both speakers are not working, not even headset is supporting. I informed them that day evening itself and gave it back for repair next day itself. At that time they have unnecessarily written in the job card that there is water damage, when i questioned that they told me that that is not significant and will not be of any harm for you. But now they are telling me that there is some issue with board and they are not responsible for that. I have given them a working phone and now they are telling that it's not there fault. Now it's more than 2.5 months they are keeping my phone without any reply. Iam student who cannot afford a new phone or change the board (Which is damaged due to some fault from there side). Now the new story is that they have closed the service centre at thrissur, kerala and sent the phone to nearby centre at palakkad, thrissur for repair. What the hell is going on, i don't know. Really disappointed with the service from an authorised service centre. I should have gone for some other brands instead of micromax. Please provide me with a reply and solution soon.
Thanking you,
