This to register my complaint against airtel 244 plan, recharged on[protected].
As per this plan, i should get 1gb data per day for 70 days + unlimited calls for 70 days. But i got 1 gb data just for the first day and unlimited calls till 2 september. And customer care service is not responding too. Please solve this problem as soon as possible. Early response is expected.
