Bad customer service

I want to upgrade my acount to private banking. Received a cal from a banker who submited my documents before he went on leaf. Abigail assisted me in his apsence. Received enail yesterday sory we cant continue go in to branch. So after numeriouse emails and calls got hold of abigail with feedback we cant authenticate u now my problem is i bought a car with absa finance not even a month back so my details must be updated but why ignore a customer whole day with out confirming the problem. Then called absa loan department as i want to take out a loan sory we cant help your acount at private bank then u call private bank no your acount not moved over yet so now im stuck and cant move forward with anything and no assistance from absa
