While there’s probably a part of luck, the way you present yourself also counts. I just corrected a bunch of mistakes in your comment before approving it and I can imagine if your email to Amazon looked the same, they did not take you seriously. Consider using the free version of Grammarly when you write online. That will do a lot for your credibility (and that’s coming from a non-native speaker that also makes a bunch of mistakes and has to spellcheck a lot of what he writes).

With the basic terms clarified, let’s get an overview of how you can best get started with building your affiliate marketing business on Amazon. As I said, there are basically two sides of the affiliate marketing equation that you can choose from, you can become a merchant and have others promote your product, in exchange for giving them a commission from the sales that they make.
As an affiliate for Boatbookings, you will receive 20% of their revenue - effectively meaning your commission will be about 4% of any sales from your referrals.  You also receive 10% of any commissions Boatbookings make on repeat customers who were your referrals. They do have a minimum charter value of 3,000 ($/€/£/etc) before commissions are earned.
