Financial hardship happens when you are unable to meet repayment obligations for a service that you're using. Basically, you're finding it hard to pay one or more of your bills.
When people sign up to a plan or service, they're usually confident they'll be able to pay the bill. Unfortunately later, due to an unexpected event or circumstance, they are unable to pay anymore. In other cases, there are those that are unable to afford the bill from the beginning. These situations are all covered by the term 'financial hardship'.
If you find yourself unable to pay you will need to tell your telephone, mobile or internet provider you are experiencing "financial hardship". The company's customer service representative can then offer you the help you need.
