Trai — jio incorrect charges

Address:

Chennai, Tamil Nadu, 600100

I'm using jio fi device which has postpaid sim got from corporate. Initially jio gave me offer for 6 months post which it introduced new plan stating to pay 399 rupees to have the plan o[censored]nlimited calls and 1gb internet per day for 3 months. Now during the month of november, three months plan is over and when we try to recharge they are mentioning that there's rental amount that needs to be paid in addition to paying 399. Now what's the use to customer to pay both prepaid and postpaid amount to have single service, when already stated that 3 months is free if we recharge for 399.

I'm unable to continue my services and jio is telling an amount for 3 months to retain and i'm not completely satisfied with their replies.
