Faulty TV

I bought a Skyworth TV from HiFi Corp Springfield branch. I spend money to have it delivered!!!!!! 3 days later it gives me software problem. Charmaine tells me I must spend more of my money to bring the TV in for exchange. Hifi sold me fault product how must I spend more money to fix up their problem. This faulty TV us their product not mine. I bought a working product why must I spend money to transport their faulty product. They must come pickup their faulty TV. It is not for me to bring it back to them.
