Welcome to Your Community and thanks for your post.
Sorry there has been a delay with your account. After documents are processed it would normally take 4 - 7 days for your card pin to arrive, followed a couple of days later by the current account card. It would be best to speak to one of the current account team on 0345 030 3170 they can check the documents were received and update you on what's happening regarding your application. The department is open Monday - Friday 8 am - 8pm and Saturday 9am - 5pm.
