Final answer:
To address a non-paying customer, one should send a legal notice, possibly cut off service, or report them to a credit agency, but should never publicly shame the individual on social media.
Step-by-step explanation:
In dealing with a deadbeat customer who did not pay their service bill, it is crucial to choose a course of action that is professional and legal. Most commonly, the initial step is to send a legal notice to the customer as a formal reminder and warning of the outstanding debt. If the customer still fails to pay, the next step could be to cut off their service, depending on the terms of service agreement. Reporting them to a credit agency is also a mechanism used by businesses to alert the credit system of an individual's failure to pay, which may affect the customer's credit score. Publicly shaming the customer on social media, however, is not a professional or legal method and should be strictly avoided. It's worth noting that a credit card company charges a specific fee for late payments, such as a $10 fee for late payment and an additional $5 each day the payment remains unpaid, as a form of penalty and incentive for prompt payment.
