FNB employees passing the bug. Lack of assistance. Lack of communication

I have been a FNB client since around 2012, most of my accounts are with FNB, My fusion account facilities was cancelled today without notification from FNB. I have my fusion account facility since February 2018, I had no problems with it until today. I spoke to several FNB employees i.e. Brain Johnson and his manager Silindile Hlongwe, none of them are able to give me a solution, they promised to call me back, but to no avail. My account is totally messed up, my debit orders etc. will not be able to go through, that is my biggest concern.

I have been in contact with FNB the whole day since 09H00 this morning, and the problem has still not been resolved. I am still waiting for Silindile Hlongwe to give me feedback, nobody seems to be able to locate her.

I really need somebody to assist me in resolving this matter, I don't believe that clients should be treated in this manner. everybody else is passing the bug. can somebody kindly assist.
