Idea Cellular — Deactivation of mobile number [protected] without any reason

This attached mail i got received from idea customer care which cites the above reason (Business exigency) for disconnection of the number. I cant even understand why my number got disconnected automatically and balance also got forfeited without stating any valid reason and without stating any fault from my side. This sounds unusual reply as there is no fault from my side and my main balance and internet balance/data pack have got forfeited and also my sim card got disconnected without any valid or justified reason.
