Yes you will have to pay your bill. Sorry it is not what you want to hear.
Chapter 11 is a good thing for amp'd corporation because they don't have to pay their bills. It is of no benefit to their customers. It is a truly amazing thing for corporations. They will continue operations and carry on as normal but just right off (cancel) some of their debts and bills. Chapter 13 is when they are shutting down and in that case you might have got away with not paying.
