Barclays is utterly incompetent.
Case in point...
Today in the postal mail, both myself and my wife received an identical form letter from Barclays. It informed us that "recently" I had applied for one of their business cards. They were unable to approve the request for that card, which they had already notified about me in a previous mailing. But they said that they had failed to provide the reason they denied me. They were now informing me that the reason for the denial was because the business had not been open long enough.
I applied for their business card in June of 2013.
It appears their working definition of "recently" is almost a year and a half. Or else they have a bit a backlog in their mail department.
