ABSA Vehicle Finiance incompetence - no ABSA APP access

Bought a new car in September with ABSA Vehicle Finance. We tried to log into the ABSA app to monitor the account as was suggested in our letter from ABSA. It failed with an error message on having dual accounts. We logged a call and after about 10 different interactions, we were informed by a senior consultant in the ABSA complaint division, that it is IMPOSSIBLE to link the ABSA app if you only have a vehicle finance account with ABSA and that we will need to go to a branch and open a transactional account. We do not need a transactional account, so we decided to go without the App. ABSA promised to send monthly statements, to date we have not received a single statement, every time we call the helpline they promised to send, and at the same time suggest we use the online App, which we were told is NOT POSSIBLE by several senior ABSA officers, includiing the branch - can ABSA Vehicle Finance decide whether it is possible to have the APP and allow us access to it???
