Problem with purchase

So this might sound a bit silly but, I attempted to purchase a rank for someone else with a prefix. I was expecting the site to give me an option to place the persons username but instead it just magically added it onto my account without me ever putting my username. Was hoping I could have the assigned prefix being [Quack] onto neonducky12, the rank Spartan. I'd like to have my champ rank back but if you want to just make me a normal dweller thats fine. sorry for the huge mistake.
