I have taken the service from A.V. Power System Sarita Vihar, Delhi. My Power one brand UPS not working due to the technical issue. So I have called this vendor and got a quick response. They have arranged a technician for service and visited our doorstep. They have checked and found some circuits are burned from inside which is not repairable. So I have other ups they have connected the ups with other ups for power supply. now it's working fine. They have charged RS 1180 including 18% GST for service. I got good service and response from sp.
