I have an online savings account with Sainsbury's bank. I tried to transfer some money out of it online, but was told that they could not verify the bank account I wanted to transfer it into (even though it was the account I'd used to transfer the money into my Sainsbury's account in the first place!) So I called up customer services and explained the situation. They took my through security questions, and said they were also going to access a credit check to ask additional security questions. The first one was who was my mortgage with. I gave the correct answer... only to be told by the customer services rep that I was wrong! We haggled about this for a while, so I'd said I go to verify it, and then call back. I dig out my mortgage statement - which indeed proves that I'm right - but when I called back I was told that I'd been locked out of my account, and that they'd need to reset it and send me out new login details to unlock it. Despite explaining to three different people how ridiculous this was, given they had the wrong information, no one seemed to care. It wasn't their fault, it was Experian's fault, because that's where the'd got the data from. So I have to wait 3-5 working days for the new passcode to be sent out, and then go through security again. I pointed out that they'd have the same wrong information, and was told I needed to take it up with Experian, who provided the report. I've never come across anything like this in my life! Any other bank / building society usually sets up a linked account when you open your account so you can easily transfer money out, and only works with security questions that you've agreed with them. I'm not sure if I'm ever going to be able to access my money again at this rate...
