Credit Increase on Credit fail with ABSA

I had app**** for a credit increase on my Credit Card. I received an email on 28 September (***) asking for my 3 months payslips which I sent through on 30 September. I then received an email on 30 September asking for my 3 months payslip again (***) which I then resent the required documents. I phoned the call centre yesterday (12 October) to follow up ***), the line was so bad the agent could not hear me on the other line and said that they were experiencing problems with the line. I now receive an SMS on 13 October saying my application has expired and I need to restart the process again. This is absolutely shocking service at a time when service delivery should be at its highest!
