Adani Gas — Cash payment not available

We are facing the problem from Adani gas for not providing Cash payment options from next month, our bank and online accounts have been hacked before and we don't trust to use online accounts anymore and govt/private companies too are using cash collection for old age retirees since they are not net savvy or comfortable sharing their account details online. Please ask Adani gas to make Cash collection center for people like us or its breach of contract on their side not letting us pay through cash and can be sued for the same when all other companies allow us to pay by cash.
