Standard Bank Service does not exist!

My Company has been a Standard Bank client for the past three years. As of late, the client service has gone from average to extremely poor - in fact, non-existent. I don't know why Standard Bank has dedicated account representatives. They don't react on e-mails or SMS's. In fact, you can't even call the Branch your account is held at. All calls go to a centralised Call Centre, and then the "fun" starts. You get put on hold forever. Yesterday, I received notification of an inbound transfer from one of my Customers. I tried 4 times to get hold of a representative to assist with the transfer. On one occasion, I held on for 57 minutes, listening to awful, repetitive "music" - no response!. Today I tried four times as well - same old story. Standard Bank is now hampering my ability to do business. They have become completely impersonal, and we, the clients, paying their fees, have become less than a number.
