India Rehab Centre — fake call received stating that he is representative from india rehab centre

I got a call from [protected] stating that he is representative from indiarehabcentre. He sent me message with online website url and process for donation. When i searched online i found its fraud. So i ignored. But that person keeps on messaging me. Then i asked him to stop messaging me as its fraud then he started replying me saying that i dont have humanity, god will not forgive me etc.,

Please take action on them.
