Worst experience on ecommerce services .I have ordered ac on 11nth of july and incorrect model was delivered. Till now nothing has been done to return and refund my order. Whenever i call to customer executive they always say we are working on your queries. Please guys go for other options and don't think they work with tata ethics. Tatacliq is fooling customers and didn't show any decency toward them if anything goes wrong.
