I called Crepe Cherie nine times with no answer and no message bank to make the required booking at their Claremont location. Then I called the Karrinyup location and was "disconnected" after telling them who I was and began stating the nature of my call. I then emailed them and they have closed the Claremont location. They said they were taking the vouchers at the Karrinyup location and that no bookings were required (I think this location might be in the food court, but not sure.) I had asked for a refund and they basically told me to use it at Karrinyup. They also said that Living Social was supposed to have updated the website, etc. LS had not.
Anyway, I got my refund from LS.
If, by chance, any ozbargainers are holding Crepe Cherie vouchers which expire in about a week, they should either go to the Karrinyup location or request a refund from Living Social Karrinyup was never part of the deal and they are giving refunds quite freely. With the option of getting deal bucks instead.
