NGO Darpan — Wanted money for a child who is suffering from cancer

I have been receiving calls from them since two days, initially they asked very respectfully .I asked about their details and all, they sent me tax exemption some other certificates immediately to my whatsap.

So I thought this could be scam and blocked them after reasearching about this Darpan in Google.On the very next they called me from another number for follow up . I asked to send them their audits and he replied how can I send when you block our number.

I answered "when you know that I am blocking your number then you should think that i m not interested and should not call me again" and he started screaming and abusing with a bad language..

I immediately blocked his call too..

I don't know how they are able to get the numbers.

We really don't know who is genuine when real needy people approach us
