One Life Care — fake donation calls

This organisation named 'one life care' had been calling me rigorously a few days ago. I was so irritated and angry at these guys that I took it to the complaint forum. They asked me to donate money immediately to help this girl child who was receiving treatment for cancer at AIIMS. They insisted that I donate right away without even disconnecting and kept on asking for my payment details. I yelled at them that it sounds like a fraud and they hung up. This is such a fraudulent attempt to extract our hard earned money. And after checking multiple forums I realized that a lot of people have been through the same. I strongly recommend to take action against this organisation and stop this illegal activity immediately.
