Poor service

I am having a problem with Madeline Ferreira from Whitfields she is handling my account she is unhelpful and when I call her she ends up hanging up the phone I have sent her emails she has never responded I told her that I have been telling her that I been on need vendor since November the 3rd which is prepaid I been recharging my water and electricity from netvendor which I can provide statements I told her that she must fix my statement called her couple of times before she went on leave she never rep**** am not happy and maybe because am black that's why she even hang up the phone on me and doesn't want to listen to me she is clearly doesn't know what she is doing the balance brought forward on my recent statement is wrong and the last statement balance is not the same I told her she must update my current statement and remove water bill because I bought from netvendor the whole month so what she did was remove and added it again and send me a statement which is incorrect again am not happy with service and want my statement to be fixed so I can pay January if this not resolved I will lodge a complain with ombudsman
