MyUS - consumer unfriendly and predatory

I shipped a small card game (never arrived) and tried to ship a battery for a Phantom 3 to South Africa. In the end I gave up and shipped the battery to a colleague who was in the United States because it was never going to happen (cost a fortune by the way). At this point I want cancel the service and cut my losses - they tell me you can't cancel until shipment arrives, so I wait and then request a cancellation. No - you must now wait 30 DAYS after your shipment arrives then they will cancel. Clearly - they want as much subscription money from their customers as possible.

By the way, their web site suddenly keeps logging me out when I try to remove my credit card details or modify my account. Suspicious.

TD;LR: This is a consumer unfriendly and predatory company - DO NOT USE THEM.
