Problem with support and account

Hello guys,

what is the story....After the warmane was hacked and reseted,I've decided to delete my current account from this website and forget about it.Unfortunaly support is saying to me that I need my old email adress for deleting my acc.The problem is, that the email is deleted and I exchanged it for other one (also here ofc).Why do they have such a big problem with deleting it when I have only other email adress.....And why is it problem ONLY here.And I also think that they started ignoring me.

Any ideas?
