failure to replace my damaged tv

I bought a jvc led 46 inch tv last year april and we received a faulty tv.we returned it 3 months later but again they gave us yet another faulty tv.the tv was sealed till we decided to use it only to find that it has the same problem as the previous one.we then returned it but this time we did not get another one.but they took it in for repairs.our problem is that what are they going to repair since the tv has never worked.and yet again we cant wait for 2 weeks for them to repair the tv.two tv's having the same problem just means the model is faulty.therefore we would like them to do something as soon as posible.
