LG AC
Board Fauld with in 2 Years

I had bought 1 no LG Split AC during the year April the cost which i had paid is 45, 000/-. Now i am facing problem that board is having the problem. i had paid so much of amount the AC did not serve me for more than 2 Years then what is the use of paying so much and getting the branded product.

To whom i have to complain regarding this. if i repair also even thought i will get some other problem in the next few month. i had asked the customer care department they are saying that the AC carry warranty for only 1 Years. What i had to do.???
