Micromax Informatics — Replacement issues

Address:

Hyderabad, Andhra Pradesh, 500004

I purchased a micromax a350 smartphone last year and on 19th december 2015 i submitted the phone at secunderabad micromax care service center. I was told i will be getting the replacement for my smartphone within 30 days and i got the phone After Approximately 70 Days and the phone i got was not new and was just another phone which had issues, the speaker wasnt working and the phone was rebooting etc. so basically after 70 days i get a phone which is worse than the phone i gave to the company.

now i have submitted the phone again to micromax care service center, secunderabad. i am told i will get another replacement. i am pissed off with the service and their employees, .

I purchased the phone in 2015 for 19, 500 Rupees and this is what i get???

This is how a company sells their product?
I want full refund!!
