[protected]. Received confirmation from airtel that the technician will be visiting on 5th but just some time before visiting hour received another message that dear customer, your service request no[protected] could not be attended by our engineer due to a technical issue.. The next appointment available for engineer visit is 10 sep 2019 07:30:00 pm-10 sep 2019 08:30:00 pm.
Is airtel expecting us to be without internet for more than a week? Any number of calls will fetch the same answer. Is this quality if service we are expecting from well known brand airtel. Writing this here because we are facing this issue in second time.
