I have been out of country only for few months and my my bangalore phone no. Got disconnected inspite of keeping it on on mobile.. However i do received messages.. Why is it so?? I would like to know the reason for being disconnected without giving prior notification sent to me... And it sound quite unfair.. Today i try to recharge balance but it doesn't work in the sense money was deducted but dint get the balance.. I try to place a call to customer care too but couldn't... Please activate it asap as it is link to my bank account... What should i do to get it activate??
