Hello! How are you? I am doing fine! I will answer the question now.
Not being able to pay back your bills will create a negative problem with your credit history, as banks and other associates will see that you cannot keep a straight and consecutive payment, will make you untrustworthy and unreliable to pay back money. This can affect stuff for when you want to take out a loan and you would be declined because of your recent credit history of not being able to pay back bills, which indicates that your credit score itself probably is low.
Hope this helped! Your welcome! I can help with other stuff too! Bye!
