WhatsApp Account Limited After Sending Messages to New Contacts

I am using WhatsApp on an IQ Z10 Lite device, and my account has been repeatedly restricted when I send messages to new contacts. This issue started yesterday. Initially, my account was restricted for 24 hours, and after that period ended, the status changed to “under review,” and I still cannot use my account properly.

The restriction usually occurs after I send messages to around 30–40 new contacts. Because of these restrictions, I am not even able to contact customer support within the app, so I have not been able to receive any explanation or assistance about why this is happening or how to prevent it.

I request that my account be reviewed and that these restrictions be removed so I can use WhatsApp normally without repeated automated limitations when messaging new contacts.
