Pillar to Post/ No responsibility

I am totally disgusted with the service SAMSUNG SA has given me thus far. I have bought a TV from them which just stopped working 2 months after purchase, and with my warranty, I have had thee most difficult time trying to get it replaced. Every agent I have spoken to at theri head offices has said they will get back to me, and to this day, I have to call everyday just to find out when I will get my TV. Its been well over 4x weeks now and everyday I get a different story about while I have all the documents for an exchange. I would just like to say SAMSUNG SA is disappointing and I wish i had bought another brand!!!
