Order no - so73788769. I ordered a mobile case for iphone 7. They sent a case for iphone 7 plus and the design is also not the same as the one i ordered. I tried to put a request for returning. It is not getting submitted on app. I called their customer care line, they asked me to submit the complaint on their customer support chat. I tried to submit it on the chat. No proper replies on the chat, the answers are un-helpful and they take hours to reply and repeat same questions again and again. Very bad experience. I want the item returned with full refund.
