Overdraft Limit Increase 2 Weeks No Feedback, No Funds

It has been 2 weeks since applying for an overdraft limit increase with Standard Bank. Application 1 was approved, required documentation sent and application expires due to Standard Bank not replying with in 7 days... Application 2 straight approved, no further documentation required, no feedback, no replies on emails for follow ups, calls not returned. Application 2 is also now about to expire. What kind of ******* service is this where something so simple expires because of lack of feedback and requires a new application every time? Please sort out your system as this is just pathetic service.
