The thing I dislike the most of this…
The thing I dislike the most of this company is that they mostly get the shipping and packaging estimate wrong. They would ask for additional charges and if you want to change it would be an additional service fee even thought it was a mistake on their side. This is the only proxy I have ever encountered making this kind of mistake without them trying to own to their mistake but doing additional charges. I hope that you would improve of this because this has happened multiple times already.
