ABSA BANKING APP BLOCKED

Good day I have challenges with ABSA there always seems to be an issue their service is poor and annoying. I have been banking with ABSA for many years but it seems like they fail to keep their loyal customers satisfied with the services they provide. My banking app and internet banking service has been blocked due to unpaid fees ??? These fees are debited on a monthly basis on my account how am I supposed to know that I am in errors when there is no even any notification sent to alert me of this. This is an inconvenience because there are urgent payments that I need to make, I am stuck I can't even go to the branch at the moment because I am at work. How do we resolve this issue, do I have to wait for another day to settle my urgent transactions? ABSA is failing us and their services are very poor this is forcing us to seek other banking facilities that are more reliable and quick to resolve our issues.
