I sent off my admenment 3 weeks ago when will I get my money?

What exactly did you send? You say "admenment"... do you mean "2007 tax return", "2007 return with previous year amendment"... or what?

As for the '07 tax filing, see here:
Where's My Refund?

ANY amended return usually takes AT LEAST six weeks to be processed.

You are only HALF way there.
