AO Smith — Inefficient customer service and disaster management

I had order an AO Smith water purifier worth Rs 20000 which got damaged in just 2 days. Still the issue is not resolved though it is being more than 2 weeks. Each time am calling the customer care they are asking me to call 10 different person. They have such inefficient technician as well as such a disaster management people. They don't know what is happening. Some people saying the spare part that got damaged is available just it need to be fixed and some are saying the spare part is not at all available. No one knows what is the actual status . I highly recommend no to buy any AO Smith product. They have such inefficient technician as well as faulty management people. It was the Worst decision to buy the product.
