Got scammed via WhatsApp

BE CAREFUL ALL.... I GOT SCAMMED BY A HACKER WHO HACKED MY FRIEND'S WHATSAPP ID. HE ASKED ME FOR A SUM OF 50000 WHICH HE SAID WILL PAY NEXT MORNING. AS I AND MY FRIEND USUALLY USED TO TRANSFER MONEY TO EACH OTHER , I DIDN'T THINK TOO MUCH AND AENDBIT TO HIM. BUT JUST AFTER A MINUTE HE AGAIN ASKED FOR MORE (70000). THEN I REALISED THAT I GOT SCAMMED. JUST AFTER THEN I CALLED MY FRIEND WHO HAD GONE TO THE POLICE TO FILE A COMPLAINT ABOUT HIS WHATSAPP ID GOT HACKED. SO PLEASE EVERYONE CALL THE PERSON 1ST BEFORE ANY TRANSITION.
