I have purchased Voltas 1 ton split ac. Its cooling effect is not proper. Besides so many eforts Ac was reolaced. But still it is not giving proper cooling. Service center personal not taking any care of my problems . When I lodged complaint with customer care, they were also not helping me. The service center canceled my complaints falsly that customer is not responding. I am unable to use my machine when in need. I will suggest to my valuable customer to not to go with voltas.
