Terrible customer service and communication

I contacted standard bank on Monday 6 Jan 2025 to request a breakdown of my vehicle finance because the reduction in interest rate is not correct. I was told it will be escalated and I'll receive a response within 48 hours. Today it's Thursday 9 January 2025 and I had to call them back 3 time's today alone. The consultants are now telling me that it was escalated to the incorrect department and it needs to be escalated again. The first consultant said he'll call me back within 20 minutes and 1 hour later I had to call back. The second consultant just went quiet after verifying me and the third consultant is asking me to wait an additional 24 hours . The level of service is honestly pathetic. If you're ever thinking of doing business with standard bank please rethink because when you need assistance they are never willing to help.
