WHAT IS HAPPENING WITH MY JIO SIM CARD?

YESTERDAY EVENING THEY AGAIN BLOCKED INTERNET AND PHONE SERVICES IN MY JIO SIM CARD. WHAT IS MORE SURPRISING IS THAT IF SOMEONE MAKES CALL TO MY JIO NUMBER, PHONE CALL GOES TO MY ELDER BROTHER'S BSNL NUMBER.THERE IS NO ANY OTHER SIM CARD EXCEPT BSNL SIM CARD IN THAT MOBILE PHONE. BUT PHONE CALL TO MY JIO NUMBER GOES TO THAT MOBILE. EVEN INTERNET SERVICES OF MY JIO NUMBER ACTIVE IN THAT MOBILE WHEREAS MY JIO SIM CARD IS IN THIS SAMSUNG MOBILE PHONE NOT IN THAT PHONE. WHAT IS GOING ON?
