Man, just call them and say that your paypal has your name but when u bought your d3 u put your 'nickname' on it.
Worked so far with my, also I've asked them what they can do about block my ip (I've said that I travel to much and I cannot call them always when I am in another country or in another computer).
and now my main account is in the whitelist, I can do everything (change computer/ip) than I wont be flagged =]
