Poorvika Mobiles — Mobile battery and heating issue

Had very bad experience with Poorvika washermenpet branch... I had purchased a VY100 mobile at Poorvika washermenpet and the sales person has explained about the product very clearly we thought okay and proceed the buying process.on first day itself we are facing battery dry issue as well as phone heating issue .
Now my wife visited and explain about issues display the sales man said no exchange facility here we having the issue we will send it to service centre and clear .we wanted to exchange the mobile immediately after purchase. But the store sales man denied to exchange and he is not at all understanding the issue. If the shop is not customer friendly and not understanding the problems of the customers its very disappointing. We bought this mobile at 25k they are denied for exchange means what who will say okay to service pls understand . POORVIKA IS NOT A CUSTOMER FRIENDLY SHOP ALL ADVERTISING AND ALL FAKE ADVERTISEMENTS
