[RESOLVED 9/16/18] Double charged in the Sims 3 Store, Customer Service says they can't refund it?

There were a couple of posters who had the same issue a few months ago, and they eventually had their accounts credited with the missing simpoints. So it absolutely is possible to get your points back. It might just come down to which support rep you happen to get on the phone. There's no reason you can't walk away from the conversation and try again later. Both call and chat seem to work fine.
