Ridiculed by a standard bank staff bank

Hi. I was at a Witbank Highveld mall branch yesterday 2018/18/01 to link my money market account to my access account, the consultant then realised that my access account is no longer working and they need to open another account for me, the consultant then suggests that I take a funeral plan and I ask why should I have to take a funeral plan to get access to my money, she then says that she will loose her job if she opens the account for without me taking the funeral plan. She then asks me very rudely when she sees that I am not buying her story for the funeral plan who opened the account for me, I then tell her that I opened the account in Johannesburg, she continues to ridicule me by saying why would I get an account in Johannesburg while living in Witbank, I tell her that I live in Joburg, she continues to be very rude, imitating my accent saying "Oh you live in Joburg" and says I must go to Joburg so I can get my account fixed because shes not the one that didn't do her job properly and then continues to lie that it is a must that I take the funeral plan.So because I wanted my account to work I took it, but I cant afford it and this will mess up my credit score please help me by advising what steps can be taken in this regard.
