Airtel — postpaid number disconnected for no reason

Address:	560103
Website:	airtel.in

I had an airtel postpaid connection that was disconnected without any notice today. When i called twice, both customer service representatives told me my visa had expired, but that is completely false - my visa never expired (Someone must have entered my visa details incorrectly). They told me to go into a store location and that they would be able to reconnect my phone there, but that also turned out untrue as the employee at the store did not reconnect my phone but instead sent a note to the "backend guys." i still do not have phone service and i've heard nothing from airtel. At this point, i'm considering giving up on airtel and moving to another provider like jio.
