Declined faulty TV return

We have always received good service from Takealot, until now. We purchased a TV from them, which was used about twice and then out of now where, when it was switched on again, the entire screen looked like a spiderweb. We couldn't see any physical damage to the screen when we switched it off. Thinking that it must be due to a software bug, we returned it to Takealot for investigation. To our shock and disbelief we were told that the screen was cracked and that they wont be repairing it. The return was rejected. Somehow between leaving our house and ending up in their warehouse, this brand new TV was damaged. I have requested that the TV be returned to me and I will have to take this up with the ombudsman. Takealot implying that we are lying about the fact that there was no damage to the TV, is a slap in the face. Technically by them choosing this route, they have taken R3,499 and provided us with a faulty product. really sad from a company that has always provided us with good service.
