Worst service ever

I bought a 55" Skyworth tv last year on the 7th of July and in February the tv just stopped working. And i took it back on 28th of February. Until today they are telling me they still waiting for head office to give them feedback. Yet they told me they don't know what is wrong with the tv. And worst part they don't communicate with me i have to call them or go to their shop. They are no help,they very clueless
