I agree, this made no sense to me. The agent connected me to a "colleague" who was rather rude in tone and adamant that the account had never been unblocked ( um, then how was I able to use the card for those car rentals....?).
I also pointed out that if the account had not been unblocked, then how did I now have a pin for it (which was set up by the agent who had unblocked the account for me).

I certainly appreciate their fraud prevention activities, but this has required far too much time/hassle, especially when compared to the ease with which other companies (Chase, AmEx) handle fraud protection scenarios.
