Unwanted Message from Unknown Number on WhatsApp

On WhatsApp, I received a "hello" message from +62 878-3927-**651. I immediately blocked the sender's number and filed a complaint through WhatsApp's complaint feature. I want to be clear that I will not be held liable if my account information is compromised and my phone number is misused, shared, or linked to any debts. I expressly disclaim any and all liabilities that may result from such situations. WhatsApp is solely responsible for any issues that arise. Receiving unsolicited messages from unknown numbers can be unsettling, so I took immediate action to resolve the situation. I want to make certain that my personal information and privacy are protected. WhatsApp should be held accountable for maintaining a secure platform and safeguarding users' data.
