Micromax Informatics — mobile phone model v407

Address:

Khordha, Odisha, 751013

I had purchased micromax mobile bearing model #v407 on 06-02-18. But the system shows problem "key pad not working properly". When i come to micromax service center, m/s saranya associates, bhubaneswar they open the system and told that the system is tampered & no warranty covered. I had complain to micromax support vide reference no is ser[protected] indicating how a system is tampered without breaking seal?

Plz be confirm
Is it possible to tampered with seal

Is micromax sold repairable mobile with seal

Is mocromax not want to give free services due to cost effective as their products require service any time.

If the above are right plz be confirm or repair/change my mobile.
