Samsung / Tv 29 Z 30 — deffective sound system not resolve after my continus complain

I have purchased a flat Samsung 29 inch TV last year 21/02/08, Model name is 29Z30 from Raipur Electronics Pvt ltd in kolkata. After twenty days I feel that there is a sound problem in my set. The sound of the TV is not clear and it is making noisy effect. I made a complain to Samsung. One of the engineers has come and looks after my problem and tells me sound system is not working properly. I[censored] watch the TV on custom mode than it is ok. Other features of the TV like music, move etc, is not supporting the sound system but I consider all the features by the time of purchase of TV and he moves away without taking my consent. Again I made a complaint to Samsung the BP. No is [protected]. This time some other person has come and see the thing and admit the problem but he told me I have to consult with my company and after that I change the sound system that is not working properly. Now I have to wait another week and then the person has come and changes the speaker of the both side. After that also I was not convinced of my TV set because that problem lies same on those speakers also. Now they are saying you watch the TV on Custom mode only we can’t do anything. I have no choice and I used to watching the TV only in custom mode only. After some time in custom mode I found the same problem I made a complain in December or jan 2009 but they never revert me back. I am facing the problem from the beginning of the purchase of the TV, they people never realized what mental pressure I have to face with my family as because they are saying not to buy Samsung buy sony TV but I have not listen to them and I buy the Samsung and face this kind of problem now again I made a complaint to Samsung the Samsung people told me sir your purchase of tv is beyond one year so you have to pay for the service and if problem of parts as well. Then I told her I have made a complain of this problem before the one year expiry time, then she told me ok I will call u latter I am just looking my authority. Then she told me ok my engineer will visit to you and look after your problem. After a one month wait I don’t have have any call and no one has come to see the problem. I just want to state to consumer forum sir please look after my case and take necessary action against the Samsung service.
