Hello there, 

I urgently need help with invoice and payment and would be very glad if I am helped. I am so not sure about how this system here works and would be glad to explain my case with receipts which I am guessing this space may not allow it. If i am directed with an email to do this straight would be a lot helpful. I have had to try to call the customer service line. But it demands me of a "personliche sprachnummer" which I barely know how to get that. It makes the whole thing a bit frustrating. I would be grateful if this message is treated as a matter with high importance. This would be a great help. Thanks and waiting on a response.

Best regards 

Deborah
