WhatsApp Harassment Complaint About Inappropriate Messages

I am writing to report and complain about a WhatsApp number that has sent me inappropriate messages today and continues to harass me. The number is contacting me through WhatsApp in Pakistan and sending messages that are offensive and disturbing. This situation is making me very uncomfortable and I do not want to be contacted by this person in any way. I request that this WhatsApp number be blocked and necessary action be taken against it so that I no longer receive any messages or calls from this account.
