Cracked TV delivered by GAME ONLINE

I bought a TV on the game Online Store. I only ordered it on the 23 November, it arrived on the 26 Nov and was collected by my son at home. I did not open it as I was still busy with renovations . To our surprise when we switched on the TV for the first time on the 14 January after renovations the TV was cracked and now Game is refusing to fix or replace it because they say I should have reported it in 7 days. I find this really cruel from Game because as an unsuspecting client who thought game was reliable, I never thought they would deliver a cracked TV. I found this very ********* from Game Online.
