I am using a micromax q372 smartphone.. I had a issue of charging the phone.. I submitted the phone on 07/07/2016, (Which is under warranty) at the authorised service centre of micromax - m/s mahavir electronics, mulund, mumbai, maharashtra.. From that day till today, i have called the service center and the call centre of micromax (Toll free number - [protected])... I hvnt received a satisfactory reply from anyone of them... They just say you will get the phone in next 10 days.. They are just running around the bushes...
I had requested for a call back from their executive's:-
1) mr. Pradeep yadav
2) mr. Gaurav singh
And others... But till today i haven't received any call back..
Infact today also i. E. 28th july, 2016, i have requested for a call back, i'm still awaiting for a call...
No one from the company replies or provides proper information... My phone just has a charging issue n i asked them why the company is taking so much of time, i get a reply from the tele executive is that you will get the phone in next 10 days... Seriously i did a big mistake buying micromax... They have a pathetic after sales service...
