BSNL — Reduced the calls and enhanced Rent-phone No[protected]

Address:

Jabalpur, Madhya Pradesh

I am using BSNL Braod Band Unlimited combo plan with Rs. 1000/- monthly charges. In this plan 450 calls were free to all network. But now BSNL says that in BSNL network calls are free and the rent has also enhanced from Rs. 1000 to 1050 without giving any notice. I pursued with the officials of BSNL but no result. Please guide me
