I called this company to repair my RO from another company. They asked me to send the photo that I sent. Then they send their technician. The technician told us that he would have to change some parts. We said we already had those parts, but he denied to use the spare parts we had. He said he would only use the parts that belonged to his company. If the RO is not from not your company, then how can you use the spare parts from your company. He denied to use the parts provided by us and asked us to give his service charge. I talked to his customer care and they also said the same thing, then we paid his service charge and he went. Third class company. Never trust these people for repair if you had RO from another company.
