Address:

D/o s manjit singh, house no 132, ward no -2, near sagar chownk vpo- shri har gobind pur ,distt- gurdaspur, Gurdaspur, Punjab, 143515

I purchased karbonn model no - a1 indian, product code - mobai-indian-4gbran[protected]fd on 28th dec 2018, through paytm by marketing company kiaan marketing.
From last 3months it got heated up much more thn previous tym and while using it for 30 min atleast, it heated up frequently and its battery swollen up. It frequently got switched off on its own. I don't know whats the matter but i think it has some internal default. Its under warrenty period. I am living in a village and here is no mobile certer service.
