Airtel — incoming call and internet not available for 5 days

Address:

600100

No incoming calls and 4g internet services not available on my airtel mobile number for 5 days continuously. On calling the customer airtel service desk, no proper response. Issue started on 23rd oct and i was told that issue will be fixed by 27th 5pm ist. After 5 pm ist on 27th oct, the customer rep (Claimed to be the highest level of escalation, his name is manikandan - people should make note of it) said it will take another 72 hours. Incurred huge loss due to this attitude of the service provider. Still i've no clue what has gone wrong. Unacceptable!!
