Over 30 minutes on hold

I am appalled by Fnb's service level. I sat on the phone over 30 minutes waiting to speak to someone about a debit order reversal. When i called there standard number again I was told that I would just have to wait for them to answer. I infirmed the woman that I have a high pressured job and as euch cannot sit on the phone for this long. She told me that sh2 cannot get anyone to phone me back
