Youth Helping Trust — Fraudulence

I got a message through whatsapp this afternoon from the number [protected]. The person on the other side said that she is Sheetal, seeking help from Youth helping trust for a kid of 6 months for his treatment of nose cancer. A photo was also provided. She said in asking for the amount in a hurry so that any person would melt and won't give a second thought before paying. Payment link for payU money and account details were shared. She was utterly desperate while asking for the money. After that I asked for more details like hospital where the baby is admitted, authentic papers and her ID proof of the trust. Then no responses came. However, we searched internet and found several complained were filed against this so called trust. And the nature of complaints are quite similar to what I am writing over here. I don't have much idea how I can put these ### behind the bars. Though I haven't paid any amount to them but I want this kind of fraudulence to immediately get stopped. If this continues there won't be any trust for the ones who GENUINEly require help.
