dashboard feeds mix up help?!?!

hi there

i tried buying a $39 membership and somehow i purchased a $19 dashboard feeds plugin???????? wtf?! i cancelled it but not happy that i have been charged and was hoping to get it reversed as you can see i purchased it and 10 minutes later i have cancelled the subscription. all i wanted was to be a $39 member so i can download a few wpmu plugins.
kind regards
Nathan
