Poorvika Mobiles — frustrated to know that there is no return policy

My husband got me an iphone se 2020 from ekkatuthangal branch, chennai as a surprise wedding anniversary gift. As i am already using iphone series mobiles i wanted to exchange it to buy iphone xr but when i contacted the customer service and the branch i received such an irresponsible answers that once goods sold cannot be replaced. Even i told them i dint even open the mobile box, it’s perfectly sealed still it cannot be replaced itseems. So that means no one can buy products as a gift from your stores. Does it really make any sense?? And do you really think we are stupid enough to spent rs.47800 for a mobile and you people are asking me to use it despite you like it or not just because it’s your fate as you choose poorvika mobiles over any other reputed mobile shops. I feel really frustrated and will never ever recommend or suggest poorvika mobiles to any one. You people are cheaters
