Consumer Redressal

Dear Sir, Need your help in this matter. Recently I bought a 39inch Croma TV which was in the display from Chroma DLF Mega Mall Gurgoan. I aske the salesman to pack and deliver it to my house within 24 hours. He told that it would take atleast 3 days and insisted me to pick it by myself if i need quicker delivery. They told if i will pick it myself they will gift me a power bank. I asked the salesman to pack it and have no ways to know the tv he packed is the same TV which was shown to me. Moreover he packed the 39inch croma tv in a 32inch samsung box. On reaching home I opened it up and came to know there a hard scratch on it and panel is faulty. I took it with my uttermost care and i know i have no means to prove that it was taken with full care. But I am pretty sure that it was faulted before hand. Here i would request you to look the issue and provide solution to me as a Consumer .
