Well it may be the W...for I am an M.
But I think that the reason that you have not been POCked is not the cancelling.
For I registered for all 3 on the
17th...and then on finding my 5000 for 5 postcard at home waiting for me
I rang on the 18th to ensure that I was enrolled in my postcarded offer.
I was informed that the other two would be cancelled.
After points starting posting...and obviously from all three I again rang and was advised that yes that had my correct one...and that they yes would cancel the other two.
So I suspect that they could not actually alter people enrolments till some software fix was prepared....and that this is what POCking does. It puts people in the one enrollment if in multiples, and if only in one, but the wrong one it swaps you.
I think that the inability to cancel, or correct, enrollments was one of the reasons why they stopped awarding bonus points....that plus the bill splitting which was going on.
