Barclays have penalised thousands of students with charges this week by accidentally removing their overdraft facilities. Usually at this time of year any graduates would be moved to a standard Barclays account but a processing error meant that around 20,000 people had the facilities removed by mistake. This could lead to costs of around £35 a day or £175 a week. Barclays have said that all the charges will be refunded but I doubt that any consolation for those graduates that have rent to pay.
