TV problems/Website useless

<p>Firstly I don't understand what the use of having an online chat because there are never agents available and I cant keep on checking the whole day. Also when I want to send an email I must select a model first and it is not showing any models. How do you make contact then?</p> <p> </p> <p>Secondly my tv has a line of white dots at the top and then white dots scattered all over the TV. The model is UA48JU6000K. I read that alot of people have this problem. Bought the TV at the beginning of the year and looks like the quality of this TV is really bad and I didnt expect this from a premium brand like Samsung. Looks like brands like Hisense and so on may be better options and cheaper as well.</p>
