I have send the scanned copy til the close date, tracking number and the original through DHL, was picked up on the 14.09.04 and now no answers to my mail due the reason of not needed "Application for Entetliment to reduce tax rate" for German residents! No answers from email@example.com please help me and make a statement the fast invoice delivery costs me about 97$. No answer is a no go.
I just found the information about the invoice in Gmail spam filter! I mailed support twice about if I had missed something and got no answer. I don't mind getting the price money late, but dropping about because of some technical error would be kind of sad. Is it too late now? Hopefully not.
