Hi, This AC of Voltas is one of the most defective air conditioner machine I have ever seen. It is totally 7 times I have consulted Voltas customer service, service centre, voltas office , but all are in vain. The company have cheated me. The AC was not giving cold air since 7 days of its purchasing. A local boy at last get the ac repaired for me. So why company is keeping so called technicians who are totally unworthy. . If any doubts , you can call me, all relevant documents are with me. I am totally frustated .
