Well the good thing is you didn't FE so you at least have the protection of escrow if things do not work out as planned. Wait and see what happens first, you may be over-thinking the issue but if you do run into problems you can ask for SR support and they will have access to all the messages you exchanged with the vendor so they will be able to draw their own conclusions based upon that and whether any other buyers have also had similar problems should they arise. Hopefully everything will work out fine anyway and your order arrive without issue.
