I used to be an avid client of Lifebooker until earlier this year, when I purchased two Lifebooker vouchers for Soca Motion classes and after calling and writing the merchant repeatedly to schedule the classes and receiving no response, I contacted Lifebooker for a refund and was told, basically, that it was not Lifebooker's problem.
I filed a report with the Better Business Bureau, and I intended to blog and write on review sites about Lifebooker's policy of "screw you—you buy from us and you're on your own", but I decided to just take the $14 loss and never patron the site again.
