LG customer “No Support service” , clueless

I called LG SA asking for advice on their nanocell tv range features , I was on the phone for 20 minutes as the representative went to read online about their product. I expected them to know their product features and be able to give me information on the spot. I had already read the information online and just needed clarity only to find that they actually don’t know their products ; they couldn’t be of any help to me in making my decision. I was given third degree when I called them on numerous occasions & they are reluctant to let you speak to a consultant and tell you to read on their website. I guess they are avoiding to be exposed that they actually don’t know their own products. Waste of my time and airtime
