Usha International — Service not given by the usha

I have buy a usha farrata fan. And the warranty in this fan is one year, but just after one month my fan is not working. I have raise a complain to the toll free number[protected] with the complain no - [protected] on dated 09 - 06 - 15 and they have given me a time for 48 hour. After 48 hour i have again call to customer care, and they have given me a extended time for 24 hour for service but i am not able to get service. Every day customer care have promised with me that i am getting service in 24 hour but unfortunately i am not geting service from usha
