Number deactivated without my knowledge

Ive missed my monthly installments for the past 4 months and Cell **** decided to deactivated my number without my knowledge. They could have at-least made me aware that my number is going to be deactivated and removed on their network so that i know unlike just deactivating it just like that. Now seeing that they decided to deactivate it without my knowledge i guess they have also terminated my contract with them so they should not expect me to pay anything going forwards.

Ive went through the contract over and over again, there's no clause saying that my number will be deactivated without my knowledge should i fail to pay my installments.

Anyway they can keep their Cell **** Service and ill move to another service provider.

Regards
