Standardbank staff arrogance are not customer service

I've been struggling with Home loans for 2 years now ,trying to understand my situation I'm in , they're call centre staff are so personal racially rude ,you don't get an attitude with a customer ,you don't get arrogant ,you're suppose to assist not attack the customer ,that's why customers have issues,complaining ,asking for help ,does not help .this *****nce of just attacking the customer is wrong.even doing a recorded phone call and hanging up is not helping ,the last time it took me more than a year to sort out my small loan debit order ,that a staff member messed up .this is so unfair .
