I recharged my prepaid bsnl mobile number [protected] with stv489 according to which i should get 4gb data per day for 90 days. But stv444 activated at my number and i'm getting 1.5gb data for 60days. I tried to call customer care but they are not responding. Where should i complaint against these frauds?
Please look in this matter and activate required special tarrif voucher to my bsnl mobile number.
