I can confirm that after I sent a PM to mochuuu with the details about how CS didn't do the refund, the day after, I got a refund for Rayman 3HD, although in the end I don't know if the game is still ours to keep, or will be "deleted" from our psn account.
Thanks to mochuuu for helping us when CS couldnt.
So I'll be sending off the following people who PMed me to Customer Service to get their refunds ont he Might and Magic and Rayman 3 HD trnasactions. They will verify that these 'purchases' took place and get the $$ back to your SEN Wallet.
From here, I will be working with reporting to pull the list of all users who accidentally bought Rayman 3 HD and Might and Magic: Clash of Heroes and get them refunded as well. I won't be capturing further PMs and will instruct CS to pull everyone affected since we've identifed the short coming with refunding the 2 titles mentioned in the first run.
Thanks for your patience on this and I'll continue to provide updates as they come.
