I purchased a Whirlpool a/c . Last week from 30th August it doesnt work so i called the service center in chennai. A man came and took some spares and kept the applainces as it is opened. He said we will come after some days to change the ^parts but no one turned up. I am calling them to service center but no response. What will happen when dust accumulates in that appliances. I am not at all satisfied with their services and products. I am 75 years old and without a/c it is very difficult to sleep in this hot chennai.
