Blue Star Ac — air conditioner

I have bought bluestar air conditioner 1 year ago, thereafter 2 months it was not cooling And giving hot air, I am giving complaint, the technician wanted my delayed until the warranty completed, now they are billing too much, still now the problem was not solved. The technician came week after two weeks, did something, but no use, the problem was coming again and again. I was gave complaint through online also so many times, but they are showing too negligence in my problem solving. Because of high temperature my both sons suffered from severe fever. Still now my problem was not solved
