I sent in my unit due to a dysfunctional right shoulder button (not wanting to fix it myself and void the warranty). I sent it by USPS and they said it would take a week and it has been over a month and the people at openpandora have not responded to my messages in a week. I don't want to think I'm getting ripped off here. What email address do I send my messages to? Since I haven't gotten a response I can only assume I'm either messaging the wrong address or somebody is trying to rip me off
