I purchased Sukam inverter last year. Last month there was an issue created in this inverter. A sparking creating in the wires of the inverter, I immediately switch of the inverter. I called to Sukam customer care and registered my complaint. On the next day, the technician of the company came to my house and checked the problems. He repaired the inverter and just charged me five hundred rupees. I am happy with his good job.
