We have bought your product from an exhibition 6 months back with warranty and guaranty. It started giving out contaminated water. We asked your service provider to check it. He showed up after 2 months and refuses to service it claiming we need to pay extra after which it will start. And stated due to the system not being used the filter is spoilt. We could not possibly use the water coming out of the system. This system can cause health issues and illness to the public after ingesting the water that it was producing. We have been calling for this issue since the past 3 months. Worst purchase I have ever made.
