disgusted in the caliber of helpdesk consultant

Today 28 November 15, I purchased an item on takealot. an error occurred during eft payment and I was told that there is a problem with all FNB customers. I called FNB upon which the automated voice informed me of the current problem FNB is having and that I must hold. A very rude and obviously lazy consultant assisted me and after i explained the problem, he told me that I must hold. I did that for a further 15 minutes which by now made by call 25 min long...still holding. Eventually he returned and was even more rude and it was very difficult to clearly understand him. When I asked him for his name and last name he put the phone down in my ear!!. This is absolutely unacceptable service from a bank such as FNB and I want this matter to be dealt with! totally poor and putrid service and I am totally disgusted.
