Appalling Service

I app**** for a readvance on my Homeloan which was approved and was reassured that the money would be available yesterday. I called their call centre daily and to ensure all was in order and was reassured payment would be made. Then on the due date no money was transferred to me. I was told it would take another 5days!!! I escalated this to the supervisor Bunkie Khumalo who refused to speak to me and I had to work through her consultant. They promised to call me back but she hasn't had the courtesy to call me. I laid a formal complaint with her manager Phumeza Mnqayi but have not received a response yet. I have been a customer of Standard Bank for more than 20 years and have never had any reason to question their integrity or honesty. I am now however seriously considering moving all my accounts to another bank and to stop doing any further business with Standard Ban****
