FNB - Worst service in my life!

I have spoken to A LOT of call centres the last few weeks, by far worst service in my life! Called to change my collection date of one of my FNB debit orders, had to be put through to the right department ten times, hold on for 10min between transfers, get to an advisor just to find out I'm AGAIN in the wrong department. Eventually after two days and few hours on the phone, I got upset and asked the advisor to rather get someone to phone me, started telling her why I'm so upset, she got rude and while I'm talking to her (Bridgette) she decided she's not in the mood for this and just transferred me back into the loop. Seriously? Unhappy with my whole experience but especially with your rude advisor Bridgette. Seeing you get thousands out of me a month with interests, I would at least expect a bit of care from you towards your clients.
