Shocking customer service!

Once again: Nedbank's inefficiency and the customer must suffer! Put on hold! Wasted airtime! Promises of return calls....and NOBODY knows how to help even when you follow their instructions. After going into my nearest branch nearly a year ago to follow the correct procedure of changing my phone number , I realized today that they didn't save my new number correctly, because an "approve it" message was sent to my old number . After a long time on the phone this morning with Chardonnay ***) she promised to call me back once she had more information on how I could be helped without needing to do the drive from Dullstroom to Lydenburg again, especially as the mistake was on the bank's side. Big surprise! She never called back. Then at about 11h40 I called again. Went through everything with Chloe who apologized and promised to tell Chardonnay to call me! Right......obviously that didn't happen. Chloe also promised that she, herself, would call me back in an hour as a follow up. No surprise here to say that she has not called either! I believe that they tell you this to shut you up and get rid of you...... Once again: shocking customer service!
