When a customer fills up at an unmanned petrol station using a debit card, the station often takes extra money out of the customer’s account as collateral. Some customers have had as much as 500 kroner put in reserve on a 100 kroner sale. Problems arise when the stations take as much as three weeks to put the money back into a customer’s account. The practice is under investigation by the consumer advocacy ombudsman, who said that it is wrong that customers have to wait so long to have access to their own money. The stations say that responsibility for the collateral practice lies with the digital payment service NETS. – TV2 News
