Voltas — Air Coller

Address: Rani Bag Collony Aleehpur, Dhampur 246761 U.P. India

I bought a Voltas air cooler in JUNE month. wheel problem on day one . I complained on 20th June. Engineer visited and replaced only 2 wheels. but this problem is the same. not resolved. After that again I filed a complaint dated[protected]. but till now[protected] any phone calls have been not received from Voltas' side. So many times I call customer care but every time they said, my technical team will coordinate you very soon. After that I received a SMS for technical visits on 04:40 PM,[protected] and after 3 min 04:43 pm I received a SMS that the complaint was closed. How is it possible? without a technical person. The complaint is closed.
I am very disappointed with Voltas service. Please tell me what I am doing.
