FNB service sucks

I have paid off my homeloan at FNB and now I have been trying to get a cancelation of my bond letter from them.It has been a absolute nightmare. I complained to their complaints department. Initially they were helpful and referred me to the relevant department. Then the circus show started again. Pls guys, I am at my wits end. Will you pls sort out my issues or do you just don't care. Seeing by your rating on Hellopetter, I am truly worried if you are even able to problem solve.
