Private Banking a farce

I have tried to get hold of my private banker , according to FNB's marketing they are available 24/7 and I cannot get hold of them during working hours.

I added a new client to my payment schedule last week and was given an error report , I sent an email to FNB and I received a call back a few hours later I was not able to take the call as I was busy with a business call , they did not bother to try again just sent me an email to say they tried and could not get hold of me. To cut a long story short I reentered the payment schedule a few days later and now both scheduled payments have gone through and I cannot get hold of my private banker to sort out the funds
