Even if we assume something is a civil matter, a service provider has the right to be upset with you if you don't pay your bill on time.

You seem to be concerned that you could be criminally charged with something. Normally your failure to timely pay the balance due on your account would be something the service provider would have to resolve through a civil lawsuit (or by otherwise convincing you to pay), but we don't know the full facts so we can't tell you if your case is different.
