I tried to apply for a credit card online, following a plug on their deal from MoneySupermarket.com. I was unable to complete the application online because it kept asking me to register using existing details I didn't have - being a completely new customer. Three calls to Sainsburys Bank later, they were still unable to offer an explanation. They did offer to do the application over the phone which would have taken half an hour. Not convenient for me unfortunately. And trying to get through to someone in customer services seems impossible! Just an endless litany of recorded messages and options for other services - but NOT customer services. I gave up in the end.
