Samsung 40 Inch FHD Smart Tv bought broken

Good day. I bought a 40 inch FHD Smart tv on 25/11/2015 in Canal Walk. The HDMI ports never worked from the start but I wasn't sure if I was doing something wrong. I called the call centre and I was referred to a place in Milnerton called Unitronics. Today I took the tv to them and they kept it behind saying that the board needs to be replaced and I will get it back hopefully next week. Seeing as the tv is only a month old I expected it to be replaced and now I have to wait for the tv to be taken apart and repaired. Is this how it is supposed to work? I expected to be buying a quality product and not something that immediately needed repairs. Not happy about this.
