Wrong Name on New Account

I approached Nedbank a month ago to open an optimum current account as I already have a Nedbank Creditcard Account for 15 years. My middle name did not appear on my Eskom statement as proof of residence so I had to instruct Eskom to change my name which I did (this was half a day wasted as I had to goto the office). I then went back and the account was opened with my full names, but the middle name appears first now, including Greenbacks. This is incorrect. Please resolve the problem immediately or I will cancel account.
