I got to say, my experience with Seven Seas shipping has been pretty good, took away the hassle whilst I was stressing about the move from UK to HK.
I sent around 16 large boxes in April using their door to depot service, thinking that it would be easy for me to find some company to lug to boxes from the depot to my flat. So I was surprised a few months later when I got a phone call telling me my boxes will arrive at the flat the next day.
All boxes arrived in pretty good order, not much dented corners, I didn't mind if the boxes were thrown around as I lined the inside of each one with heavy duty bin liners and wrapped everything with clothes and the huge roll of bubble wrap they supplied.
I didn't get hit with any hidden charges, no customs tax on delivery.
In January this year, I still had a few suitcases of stuff I needed to send over. Being now based in HK, I ordered 8 boxes to be sent to my father's address in UK, which he duly loaded up. I received an email a few days after pickup that I didn't contain a copy of my passport. What with the time frame I was working with, and the logistics of getting a scanned copy to my father in time, I accepted them charging me for not supplying a copy of my passport.
I find that every time that I've had a need to phone or email them, the response has been pretty good.
