bad service

on the 29/09/2015 I have app**** for a credit card , Absa phoned and said I do qualify for one and I only need to send my ID ... 9 days left and then it will be a month... they send me emails that I have 2 days to send proof of income and if I do not send it they will cancel my application ,,,, when I send it 6 days after they tell me that they are still waiting for my proof of income but I have read reports that they have received the email with my documents... when phoning in at the call centre all ask me why do I need to send that it will only be my ID as I bank with Absa so there is no need for it????<br> I send emails and calling in to hear what is going on and nobody can help me they say they will come back to me but they never do... what is this service really do I need to switch banks?
