Airtel Digital — complaint regarding discontinued my pack before it expired

Address: Karnal, Haryana

Dear sir
My airtel digitel customer id is [protected]
I has recharged it sep-2018 for 10months package those offered to me by airtel. But on 7feb-2019 airtel stoped its service yet its valid for july-2019, but now how they can stop it.
I call customer care about it. But customer executive says it happened according to trai new rules. They stoped my service before it expire. Please solve my issue and restart my package those i got after offered by airtel. They are cheating with customers by trai refrence.. But i know trai is for benefition of customers. Not for loss.
Customers last hope only trai.
