We searched every where in Kolkata for a oxygen concentrator .When we almost give up my brother in law found this site. Hello beta. In the time of crisesno body will help any one without a proper price. But Hello Beta gave us a concentrator for free. They probably save my mother’s life. I don’t know whether god exists or not but angels do. The help they are providing to me is unimaginable. For the support they are providing to me I am eternally grateful. And I can tell you for sure that millions of people are great full to. Hope they keep up this good work. And regarding money they will not ask you for a rupee. But oxygen concentrator are not cheap. So i am requesting anyone who got help from Hello Beta please donate. So that more people can be saved. Hello beta truly understand how precious a human life is. Thank You once again from Forever great full son Subhankar Sengupta. Patient Maya Sengupta. Brother in law Dibyendu Dey. Forever great full daughter Sangeeta Dey.
