Utterly disappointed in FNB service level

With all the trouble I am having with FNB, I went to Carnival Mall branch on Saturday and my problem was still not resolved, they also just made me call in, and a branch manager that did not help at all...whereby I was put through to the collections department once again and no answer until 12, whereby I was told that it was out of office hours. I received an email from Natasha from credit cards department and it is still not resolved. This morning I sent an email again to call me, and up until now nothing. As I urgently require assistance... I tried calling collections department this morning from 8am and called 11 times, the calls were answered, but it would help if the staff that actually work there, would actually speak to you and not breathe into the phone and keep quiet... I cannot Express the disappointment in FNB and the lack of interest to assist anyone... Not a care for their clients or customers.... Well done FNB. YOU WERE ALWAYS MY RECOMMENDED BANK AND NOW ALL I WANT TO DO IS CHANGE BANKS, BECAUSE OF THE INCOMPETENCE AND LACK OF INTEREST IN CLIENTS
