Rob,
Unless I missed it, you never said if J&B has is right now. Are they going to ship to your current address, or do you know. Suggestion,.....in the future you might want to get an email conformation from J&B, or anyone else for that matter that verbally says they have made the correct. If you have an email conformation from them saying they have made the address change there will never be any doubt who made the error. What plans do you have if they say they have no record of you calling to make the address change?
Always get a written conformation.
How far away is the camp? Can you call anyone at the camp to arrange a pick up? Just a thought.
I hope everything works out well for you. Keep us posted.
John
