Inaccessible and Bad Service

What mist I do to through to Wesbank. You don't answer you calls (***) since this morning 11:49. I have sent an e-mail to ***, which refers me to the APP, which sends the OTP to my old number. Meaning Wesbank didn't update my profile during last car financing application.

My call then get answered eventually at 13:47 by Tyrese who then transfers me to some "Nathan" guy who tells me to call ***. I get to the answering machine that tells me Wesbank has to many calls today. Then Lebogang tells me that she cant help because she cant update my cellphone number because the one you have on the system 073***0420 is the old number.

Later at 14:01 spoke to Camelien who then wanted to transfer me to the APP department because the new number 081***4850 is on the system but not updated on the APP. The line cut-off before she could transfer me.
