I have sent Amazon a nice polite message because I was tired of waiting for a review and they released my money and messaged me back within 24 hours. I think if you are nice it is OK to ask them to speed up the process.
You should be happy its right after. that means a couple things which are its good news for you or you didnt sell much during your last review and started selling after it was over.
Seeing that you just passed 1 it should be easy to pass a second
I have back up, i have some real details which i take slow, and some ghost....just it is annoying....oh well, i am going submit all tracking numbers etc etc...just have to wait it out.
I can bet its annoying but I had an account in early 2011 that went into reviews 5 times - all legit sales so I feel the pain
Did they ask you for copies of receipts or invoices?
Sometimes they just ask where you are getting them Then Amazon will buy form the same supplier to sell. I have a friend who never gives the real source because of this and apparently they never check. At least for him they didn't.
