i have prepaid sim.. recently i had recharged for 777. the sms cost for rs 1 paise per msg. but suddenly it started costing me 1 rs per msg. so i called up customer care. they told me to go for 31 rs recharge so that i will get 10 paise per sms.. According to them yest i did for 31 rs recharge but still it costing me 1 rs per msg.. why it is happening.. i tried to call again to customer care on 111.it says me “that number not listed”. than some suggested me try on 222 but same thing “that number not listed”. is the customer care number is changed…
