Asking to re-send the same documents

Good Day,<br> <br> I app**** for a Credit Limit increase. All my documentation has been sent as per request. Today I followed up due to not receiving any response.<br> I was advised by the Consultant that it was declined due to affordability which does not make sense as I have NO debt.<br> Then i was advised I need to re-send the documentation showing proof of income to consider a temporary increase. This does not make sense as they already have all my statements etc which shows proof of income. Why do I have to re-send to consider a temp increase?<br> <br> Not the customer service I expected from Diner's Club after being a member for almost 5years.<br> <br> Very disappointed.<br> <br> Rudi
