credit card application a total nightmare

I have been trying to increase my Kulula CC limit for over a week now. I supp**** all the information to ********** and no one can find any information on their systems. I get transferred, cut off, transferred passing the buck from one person to another. BACK AND FORTH BETWEEN FNB CREDIT CARDS AND THEN KULULA CREDIT CARDS for almost an hour today with no results. Nowhere on your website is there any information to where documents must be forwarded to or how to reach a person who speaks proper English that can actually assist. No one and nowhere is there any info whom to call or get in contact with finding out what the application status is except the f@@#$ing call centre that is useless. Is there any person at Kulula that has the mental capacity to sort out a simple application or not?
