When I buys this Voltas Company AC for my new House. Its a very poor and bad customer service. I am very dis-pointed with voltas company. When talk about installation for technical engineer. I was told installation charges will be 1500 but was charged 5000. But pathetic installation done by technician, Its Very to much charges. The people who come for installation try flea sing you by recommending and buying unnecessary material at a very high cost. I try two toll free customer service numbers are always engaged and do not work. Very Poor Service ever. Though the ac cools good whenever it cools but when in low voltage conditions it does not cool at all.
