Poor service

I bank with FNB, we have a home loan with them, I was shopping around and was offered a better deal to move my bond to another provider, I called FNB to find out if they can at least offer something similar or better since they are my personal bank. The lack of knowledge and willingness to assist from FNB is shocking, the staff don't really seem interested to retain me as a client, instead of offering me solutions they are giving me excuses. Very dissatisfied.
