Good call. If you are unable to reach agreement with the vendor SR support will adjudicate on your behalf and they will not look kindly on a vendor asking for you to send identifiable information unencrypted. Go back into resolution and update your claim including your concern regarding being asked to send your shipping details unencrypted and request the refund you think you deserve. Your funds will not auto finalize however I cannot say what resolution SR support will decide upon, that will be their call. Hope that helps.
