WHAT HAPPENED TO MY WHATSAPP?

JUST NOW I CHEKED MY THIS SAMSUNG MOBILE PHONE AND FOUND THEY REMOVED THE WHATSAPP APP FROM MY MOBILE PHONE. I DOWNLOADED THE WHATSAPP APP. BUT COULD NOT LOG IN AS I DID DID NOT RECEIVE THE VERIFICATION CODE BECAUSE THEY YET NOT RESTORE INTERNET AND PHONE SERVICES IN MY JIO SIM CARD. MY WHATSAPP IS  IN MY JIO NUMBER. I AM REALLY IN A BIG PROBLEM. THEY SHOULD IMMEDIATELY RESTORE INTERNET AND PHONE SERVICES IN MY JIO SIM CARD SO THAT I CAN OPERATE MY WHATSAPP.
