LG - blaming consumers for damaging devices when they deliver damaged units

I bought a new TV from the ebucks store - LGUK7550. It was delivered damaged. Upon opening the box I saw that the right hand side of the screen was completely damaged, cracked and the LED screen was out of the bezel I sent the TV back. I have been phoning and emailing for a response for over a week now (TV was collected Tuesday evening 21 May. I called again this morning as I do every morning to get a response from Ebucks and they escalate and say someone will call me back before the end of the day. From Wednesday last week NO ONE has contacted me and I have been left in the dark! I called again this morning and I was told that the supplier - LG has rejected the return stating the it was client negligence and that I damaged the TV I am so very angry with how this has been handled and accusing me of damaging the unit. If I had damaged it I would have just claimed from my household insurance and got a new TV, however, that was not the case. I dont know where else to turn to or what to do but I signed up to HP today to submit my complaint to try and get some action as I will not accept the outcome of this issue
