AC not working properly

I purchased an AC dated 24/03/2014, having Model No. LSA5UR2A, Split AC. That was not working properly and registered the complaint on 19/05/2014 with LG customer care center, but they are not providing absolute solution. I am suffering too much from LG split AC and not recommended any body to purchase AC of LG company. My contact No. for further inquiry is 09467534249.
