User blog:Ash-274/Zynga screws up the RP pricing

I click the button that says "Buy for 9 Reward Points" and it says (and deducted) 12 reward points. I contact Zynga and they appologized and said they would credit me back the missing RP's. Nothing happened. I contacted them again to inquire when I would get the credit and they repeated the same message. 48 hours and still no credits. Bad form, Zynga.
