Hassles changing title from "Miss" to "Doctor"

I am attempting to change my title as I am now Doctor and not Miss, I have been trying to get information from the online secure chat to save myself inconvenience. The consultant has no idea what proof of title is but is asking me to take it into an fnb branch, I asked, Is this my degree certificate? she then tells me to take in I.D and proof of residence, The I.D does not designate "miss, Mrs or doctor" so this cannot be proof of title, she then asks me the reason for change in title? because I am now Doctor, I am nt Miss or Mrs, I have worked hard for this title and I am tired of my messages and statements saying :"dear MISS Maikoo". Such pathetic service!
