I was approved for a credit card. I then tried to activate the card online and register for online banking at the same time. It accepted my details but when I went to login, it said that an error had occurred and it looked as though I somehow hadn't completed the process. I tried to complete the process but was told 'invalid credentials'. I then tried the 'forgotten details' route but was told that the details I'd entered were incorrect. They weren't. I tried this for two days. It took forever to find a number to call and then I was held in a never ending loop. When I finally spoke to someone, they were less than helpful and told me there was nothing they could do to help and I should just keep trying. I've now been trying for three days to no avail. I'm calling again to cancel my card (if I can get through?) and apply for a card with another provider - I will never bank with Sainsbury's again.
