flawed process

I app**** for a credit card limit increase and have been provisionally approved for the increase. There is a new process whereby one has to send three months bank statement together with a letter from my wife authorising the credit limit increase. I find it ridiculous as I bank with Absa and there should be some common sense as to not request for my bank statements. This inconvenienced me quiet a bit as I had to get these documents scanned and emailed to Absa and this costed me money. I app**** for the credit limit increase on the 19/12/2015, to date I am waiting feedback. I called the credit card division and they tell me that there is a backlog, how is that my problem!! And the consultants give me a different story whenever I phone. One mentioned it takes 3-5 days, another mentioned 5-10 days. I honestly cannot understand why it would take so long when I've already been pre-approved. I always received good service from Absa but once in a blue moon, employees tend to slack a bit.
