Pathetic Donna New Accounts process and procedures

I app**** for a Store Card with Donna at the start of December. I completed the application and waited about a week for feedback. After a week I called in and was asked to send my latest payslip and a copy of my ID. I sent it through and a few days later I was called and told that there was an issue with my payslip and I should send through 3 months bank statement. I sent it through immediately after the call and received an sms a few days later stating my account was approved and that I should go in store with my ID to collect my card.

I went into a Donna store and the sales lady (she was very friendly) had problems with issuing the card. She made a call to the accounts department for assistance and I got put on the phone to verify details. I was asked questions about my current credit card balances. I cannot off the top of my head remember my balances so I gave estimates of what I could last remember. After the call I was told they could not activate my card and that I should submit my 3 months statements AGAIN so forensics could have a look at it. I'm ASSUMING I answered one of the security questions wrong. But it is still very inconvenient. I sent my documents through with my ID multiple times. I was in store with my ID. My account was approved as per the messages. So why now should I need to send my statements AGAIN?

Never in my life have I struggled like this to open an account.
