Airtel — airtel digital and mobile services

Airtel digital :
Company has changed my yearly plans to monthly plans all by itself. It did not inform me or update me with the details. It just happened that i called up to complaint regarding the digital network issue and i was told regarding this. Airtel does not stand on its words.

Airtel mobile services :
I always face network issues and my mobile data hardly works but myairtel app displays 330.39 gb free and is being carried forward. Airtel does not work on issues and never mails the conversation details for further proof. The people out there hardly understand the conversation. They charged me wrong for my international roaming as well and did not refund the amount.
