Inaccurate ABSA credit card statement

My ABSA credit card statement on the app shows that 42 of my last transactions are still PENDING. Hence I never don't know what my balance is! These transactions go as far back as the middle of August. I phoned the credit card division and they say that only 6 transactions are pending. They advised me to delete and reinstall the app which I did, but the problem persists. Credit card division says they are unable to assist.
