The worst customer service I have ever witnessed

A debit order recently went off my account from Nedbank (Nedic), I then contacted the number that was provided on my online banking. I spoke to +-5 people. The first 2 people told me that they will transfer me to the Nedic department, the 3rd person told me that there is no such department like the Nedic department, she advised me that I need to contact my bank and get a user code and sequence number. I then did that. I phoned Nedbank again and was advised that I need to call my bank again and tell them to log a trace on some system. I then informed that I would like to speak to her team leader or manager, I was kept on hold for 10 minutes, then the call was cut. This is the by far the worst customer service I have received. I then speak to a Team Leader only to be given a number for Ned Insurance that DOES NOT EXIST...
