Hi
I found it easier to get a response by asking for points on the non uk part of the DIS site.
If you are a DVC member you can ask as we did for them to transfer the points to you so you can make the booking
if a non dvc member they have to make the booking for you
we also offered to pay via paypal which seemed more acceptable
We have only done the once and as you can imagine were apprehensive but all was sorted within about 3 days of me putting my request on the boards
good luck
