Havells India — False promises and fraud company

I bought Havells WP Gracia Alkaline Hot Ambient on 26 April 2023 from Bajaj electronics at Panjagutta Hyderabad. When this product was in warranty no technician turned up for the servicing of the product. It was promised that we would be provided with free service within the first year of purchase. But no one came. Now exactly at one year the purifier started showing error. The technician asked for 500 rupees and gave him and changed the UV LED but again it started showing the same error. I’ve called multiple times. After multiple calls and their false promises a technician came and again is putting up a bill of 7000 rupees to fix the purifier. We were no way responsible for all this. They put up false advertisement and rake in lots of money from the public. The customer service is awful.
