Airtel — airtel pre paid outgoing call no balance, in spite of having a valid unlimited outgoing calls pack

Address:

560100

My airtel pre paid no. [protected] and [protected] which are both on valid unlimited pack of rs 199 and are valid til 26th march 2019, i see no balance to make a call.
Airtel unlimited packs don't work more than 2 weeks, for making calls. The pack validity period is 28 days.
This is cheating and fraud by airtel and airtel should why its customers should not sue airtel in court for damages. The damages for cheating practises could run in millions
