validation department delaying my application from another bank

I app**** for a credit card with ABSA three weeks ago and I bank with standard bank and apparently my application has been delayed as they cannot velidate my information because my bank is not responding or they can not get hold of them which is standard bank in this case. can someone do their job and assist when other banks want to validate information. I'm so dissapointed with standard bank lately if its not the systems that are not working every month end its my card that declines when fund are available then I'm charged for returned payments.
