Airtel — Landline no response from customer care for 4 days

Address:

chennai

Whenever i try through the airtel app is says there is no issue found but i am unable to use internet .
On 16/11/2021 i raised a complaint with airtel through customer care and they said there is an outrage in my location and will be resolved in 4 hrs on the same day but no use
After regular follow up nothing worked a engineer called from egmore chennai and he said by mistake it was assigned to him and he closed the complaint without my consent. After which i had also mailed to airtel customer care E Mail ids for which they never bother to reply .
Today on 19/11/2021 again i called to customer care they still say there is an outrage in my location and they will assign an engineer .

Very shamed of airtel as for billing related mails they send so much mails and communications but when it comes for service they never bother.
