I paid all amount fofr the bill generated for 20nd Dec2007.Means after that am on raoming. I can see right now that the unbilled amount is 7307. 2 days back I got a call from no. [protected] that the amount exceeds 15000(My credit limit is more 13000 something. and my call is barred now. yesterday I paid 8000 Rs. but nowhere I can see the amount of 15000. even the contacting with the customer care they are not able to tell me abount this amount. Instead they kep telling that I will be contacted for this. Call from no. [protected] who told me the amount is 15000 means they have access to see the information but the customer care is saying that the unbilled is 7307. I can pay the amount but according to me it cannt reach 15000 and so I have paid Rs 8000. I need clarification on this.
