Can you assist customers with payslips ornot

When tou apply for Absa credit card and have no payslip but offer you credit card in any case using your bank statements. Why is it that when they offer you a limit increase they would not accept the very same documents they used to process your credit card application. In October I app**** for limit increase because they had told me I could qualify for one. I sent my bank statements and they acknowledged receipt to my surprise in few days they claimed to have not received the documents which I re sent and then got a message that my application has expired I need to re-apply. I did just that last week Friday and was told it would take 2-3 day i sent my bank statements through but I have had no feedback to the application except for the usual ‘we have not received your documents’. Which I have since re-sent twice. Absa must stop playing with the customers’ emotions especially those with no payslips if you can open an account submitting yourbank statements and they can approve that what makes them think you will have a payslip! The service is useless!
