Regarding the box being open, I cannot bear responsibility, because when I shipped it, it was sealed. This is post service problem, so if you had submitted a picture, there would have been a compensation. Only regarding the missing warranty, I took the responsibility on behalf of the maker and issued a refund of $300.
Regarding b, it's as you say.
In order to acquire the document, the serial number is required. I'm expecting your collaboration so that I can deliver it faster.
It will arrive in my home in 7 to 10 days after the submission, so it should get to you in 10 to 13 days.
I appreciate your understanding.
