Suspicious WhatsApp Message Sends Money, Raises Fraud Concerns

I am writing regarding a suspicious situation that occurred today on WhatsApp with the account registered to the phone number +62831. Someone contacted me via normal WhatsApp messages, sent me money, and then told me not to contact them again and to simply withdraw the money. I did not send any money back, and I did not share any personal or bank details, codes, or documents with this person. Because this behaviour seems very suspicious and could be related to fraud, money laundering, or an attempt to use my number or identity, I am very concerned. I kindly request that WhatsApp investigate this situation and the account that contacted me, and take the necessary actions if there is any abuse, fraud, or policy violation. I also request that my account and number be checked and kept safe so that my number is not misused in any illegal activity.
