If you have ever failed to pay a bill on time, received a payment order or been operated, you may be registered as not creditworthy in a data collection of a credit, business and commercial credit agency – even if the whole thing turned out to be a misunderstanding. It may therefore happen that you are refused a mobile contract, for example, or that a mail-order company is only willing to deliver on a cash-on-delivery basis.
