Damaged Samsung 32 inch TV Brand New from Box

We purchased the abovementioned television on 01 July 2015 at the said branch and was not informed by neither the salesperson nor the cashier that house and home has a 7 day return policy. The first time we heard about the 7 day return policy was when we returned the television on 25 July 2015 and the reason why we did not immediately open the television from its box was because we were busy with renovations. We were told that the television has to be sent to the repair centre for an assessment and only then we will know what the way forward will be. We received a call from Mark on Friday 31 July 2015 and was informed that the television had physical damage and he was adamant that the damage was caused by us. How can this be? We went to the repair centre and asked them how can they say for sure we have caused the physical damage and they said they never said the customer caused the physical damage. The lady printed me a copy of the service order sheet and it did not state that we were responsible for the damage.. The report states physical damage. This means the damage could have happened in transit from the factory to the store, in the store or anywhere. I demand a brand new TV
