It is a nice experience. Recently I communicated with Om Sai Service for repairing of my Samsung double-door refrigerator for not getting switched ON issue. They helped to provide details regarding the service and charges. They send me 1 technician on the same day, that technician came and checked the refrigerator. He informed that there is some earthing issue because of that it is not working. They quoted me RS. 1000 for service and RS. 200 for visiting charge. For me it's very first time with them, I think their charges are a little high. Overall I am happy and satisfied with the service.
