Holding to Call centre for 30 minutes

Good day,<br> <br> i went to Nedbank to trace my debit orders that was going through on my account, i was referred to contact call centre without success, i have been holding for the response for almost 30 minutes and i waited for the statement as well for 30 minutes, i just felt there was not enough resources to attend to our request.,i spend the whole one hour in a bank i didn't even get any of them
