WhatsApp Not Working - Urgent Fix Needed!

My WhatsApp has unexpectedly stopped functioning, and I'm unable to send or receive any messages on my number 9100129***. I’ve gone through my internet connection, reinstalled the app, and even attempted to log in from a different phone, but nothing appears to work. It's quite frustrating since I depend on WhatsApp every day for both personal and work communication. I’ve reached out to support, but I haven’t received a clear answer or solution yet. I really need my account to be up and running again as quickly as possible.
