Received Suspicious Message from Foreign Number on WhatsApp

I recently received a message from a foreign number, +880 16 0639 1443, starting with "Hello, sorry for bothering you," followed by several unsolicited business-related messages. I have blocked this number immediately and did not respond to any of the messages. However, I am deeply concerned about my account security and privacy. If my account information, phone number, or any other personal data is misused, or if any debts are falsely created under my name, I will not take any responsibility. I hold WhatsApp fully accountable for any potential misuse or security breach resulting from this suspicious activity. I expect WhatsApp to take swift action to prevent this type of intrusion and to ensure user safety.
