I play Drakensang Online.
On January 30th (2014) I logged in to find that storage lockers were on sale. Having purchased "all the lockers" for my other two characters, I purchased it for my third ($27.99 USD).
On login, I got the 'package' delivered.
I got a message saying that I had already purchased this package (not true for this character) and was credited with 20K game currency.
If I had chosen to purchase game currency, that $27.99 USD should (according to their own store) have given me 24K game currency.
I filled out a support ticket, got no response. Two days later, submitted another one, and have been given a robo-message saying I received what I paid for.
I have now filled out a third ticket. As per the others, screenshots are attached but this time I had to write a note and take a screenshot of it to send it, as the reporting form has no space for descriptive input and can only have 3 attachments, limited to a few image file types.
If it goes no where (or worse), I'll call the San Francisco office @ 1 415-821-8100 and raise the roof.
Monetary Loss: $32.
