How many time should I resend the same information?????!!!!!!!!

I have been trying to increase the limit on my Discovery Credit Card for the last two weeks. It has been an absolute headache and nightmare dealing with their credit approval department. I loaded all the required info on their website while completing the application. I was then requested to resend payslips which I did. I have sent Discovery my payslips 4 or 5 different times. I have sent them my acceptance of the quote for the 3rd time....and still they notify me today that they require additional information and then have the audacity to tell me if they dont have my info by the 3rd of March, my application will be cancelled. PATHETIC Discovery!!!!!!!!Stop your automated responses and provide a freakin personalised service FFS!!!!
