My T24 mobile number is [protected] there was a balance of rs 252 on 5th april as per the last msg received . on change of phone it became zero called on your customer care and people were hopeless they didnot knew anythg and were talking rubbish even after my repeated request to tell me details there is amount has come. firstly the phone was majority times on hold and 1 customer care exceutive piked the said only 80 ruprrees deducted for internet and then said i need to talk to senior transferred call and i had to wait fr 5 min senior she was equally hopeless and told me spend 25 rupees and get your detail. If you keep deducting free balance without any logis what is the use of giving it. My ph number donot have internet access and rest 252 ruppes details is still pending.
