I finally got an email from Sony. Took a bit longer than the 7 business days but I have my money back so I am not too upset. Now I just need to try purchasing the game and installing again. I'll let you guys know if I run into the same error again.
|Snippet from Email
Many Vita owners have been plagued by the C2-12383-7 error code when attempting to install certain Vita games. I myself have not been able to install Super Stardust Delta. After yesterday's Playstation Network update with no resolution I decided to call customer service to get this resolved. You can find your customer service number in the Playstation Store along the very bottom in the about us tab.
I'll let you all know if I can install the game next week.
