That is insane! 8 times and no-one met you? Does
ABD have an explanation for that?? For one thing, you don't have to "purchase" the transfers, they are included with your ABD. I've done 11 ABD's and I've never had them not standing there outside of customs, waiting for me, except for the one time my luggage got lost by the airline, and it took me SO LONG to report it, that the representative had taken the other family out to the driver, and then came back for me, and took me to a taxi. That wasn't their fault. I would have a serious conversation with your TA as to what it is they're arranging for you and what details they are giving ABD.
