Rude consultant

I have been trying to open an ccount with ackermans ,I was requested to send through Proof of Income ,I hav since then sent it ,I have recieved acknowledgment of reciept from a 'lucinda Mathee" according to her email signature ,the very same person wrote to me again requesting the same Proof she has said she recieved,she has even called me there is nothing she can do if i dont play my part even saying I can close the account if i iwish ,is this how you treat your customers?
