Application for Kulula limit increase

I app**** for a credit limit increase for my Kulula credit card on the 7th of May 2015, which was approved pending the submission of certain documents. I mailed the required documents and waited. I made numerous calls to confirm the receipt of my documents, only to be told that there was no application captured, but that my case will be followed up. On Friday the 15th of May, I phoned again, with the same response, there is no application, but later that day I received a mail that my application has been found and that is has been sent to second escalation. Needless to say, another 24-48 working hours have now been added to my application. On the 18th of May I phoned again. This time I spoke to a supervisor, who assured me that I would hear back from him once the system is back online... I take it the system is still offline!!! The turn around time for the application was promised to be 3 to 6 working days, but here I am, still waiting for my application to be loaded and to receive feedback from the card division. Poor service perhaps or lack of interest in what the customer requires?
