Never had any problem so far. In fact the carton that was stopped at the customs office was from an order that got messed up and they only sent 1 carton instead of 2, and after clearing the matter they did ship the missing carton.
Also, what guarantees do I have that you're not lying because you wish to get another 4 cartons for free? After all they have no tracking number. Would be easy for you to just say you didn't get them.
So far, I can't complaint about their service. Maybe my opinion will change on the future, who knows, but I'm not going to start creating problems and rising suspicions when I have no reason for it.
I've been as reasonable as possible, but it's been more than seven weeks and I'm still without product or coin.
